This educational package includes two 3D printing modeling methods. The first method is based on the use of subroutines and Python scripting. After an introduction to the 3D printing process, the first method with all of its detail is explained; then, there would be two workshops for this method; the first workshop is for the 3D printing simulation of a gear with uniform cross-section and the second one is for a shaft with non-uniform cross-section. The second method uses a plug-in called AM Modeler. With this plug-in, the type of 3D printing can be selected, and after inserting the required inputs and applying some settings, the 3D printing simulation is done without any need for coding. Two main workshops will be taught to learn how to use this plug-in: "Sequential thermomechanical analysis of simple cube one-direction with LPBF 3D printing method using the trajectory-based method with AM plug-in" and "3D printing simulation with Fusion deposition modeling and Laser direct energy deposition method with AM plug-in".

It should be mentioned that this subroutine includes gradual progressive damage based on the energy method. This complex subroutine could be used for static and dynamic problems.

Pipe Soil Interaction in Abaqus

 230.0

Pipe Soil Interaction refers to how buried pipelines and surrounding soil respond to loads and dynamic events, crucial for assessing the stability of pipelines used for water, gas, and oil distribution. This tutorial package includes six workshops that use Abaqus to simulate various soil-pipe scenarios. The tutorials cover the long-term load capacity of pipe piles under axial loads, and multiple simulations of coupled Eulerian-Lagrangian (CEL) explosions near or inside steel pipelines buried in soil. These simulations employ advanced material models like the Johnson-Cook plasticity for steel and Mohr-Coulomb plasticity for soil, along with the JWL equation for TNT explosions.

Workshops focus on both external and internal explosions, exploring how blast waves affect pipeline integrity and soil deformation. The tutorials emphasize critical aspects like stress, strain, and damage mechanics, offering detailed insights into pipeline behavior under extreme conditions. These simulations help engineers analyze blast loads and optimize the design of buried structures to withstand destructive forces.

Brittle Damage in Abaqus | Brittle Cracking Abaqus​

 240.0

Brittle materials, such as ceramics, glass, and concrete, break or fracture easily under stress without extensive deformation. Unlike ductile materials, brittle materials snap suddenly, lacking the flexibility to rearrange their atomic structure under strain. These materials have low tensile strength but strong compressive resistance, making them vulnerable to brittle cracking Abaqus simulations when stretched or pulled.

Understanding brittle material damage is crucial in safety-critical fields like civil engineering, aerospace, and manufacturing, where unexpected fractures can lead to catastrophic failures. Simulations help engineers predict when and how brittle materials may break, guiding safer design choices. Brittle cracking Abaqus can be modeled using various methods, including the Johnson-Holmquist (JH) model, XFEM, and energy-based approaches, each suited to different types of loading conditions.

For dynamic, high-strain applications like impacts, the JH model is effective, particularly in Abaqus/Explicit with specific damage parameters. For general crack modeling, XFEM is versatile, allowing cracks to form naturally without predefined paths. The energy-based method is useful for slow-loading scenarios, defining an energy threshold for fracture initiation. Each method requires careful input of material properties, mesh refinement, and load conditions to reveal potential failure points and improve material performance in real applications.

Introduction to finite element method (FEM)

The finite element method (FEM) is a powerful tool used to analyze complex physical problems in engineering and science. Imagine you have a car engine – a very intricate system. FEM helps us understand how it behaves under different conditions.

Here’s the gist:

  • Divide and conquer: FEM breaks down the entire system (engine) into smaller, simpler pieces called finite elements. These elements could be tiny triangles, squares, or other shapes, forming a mesh over the system.
  • Math magic: Each element has mathematical equations describing its behavior. By applying these equations to all the elements and connecting them together, FEM builds a large set of equations for the entire system.
  • Computer power: Since solving these equations directly can be overwhelming, FEM relies on computers. Powerful software crunches the numbers to find approximate solutions for the whole system.

FEM is particularly useful when complex shapes or material properties make it difficult to solve the governing equations analytically. It’s widely used in various fields like:

  • Structural analysis: Predicting stress and strain in bridges, buildings, or airplane wings.
  • Heat transfer: Analyzing heat flow in engines or electronic devices.
  • Fluid flow: Simulating how fluids move around airplane wings or inside pipes.

FEM provides valuable insights for engineers and scientists, allowing them to design better, more efficient systems. While the inner workings involve complex math, the basic idea is that FEM tackles tough problems by breaking them into smaller, more manageable pieces.

1. What is Abaqus and Abaqus CAE?

Abaqus is a software suite specifically designed for finite element analysis (FEA). FEA is a powerful computer simulation technique used by engineers to predict how complex structures will behave under different conditions. Imagine a bridge design – this software can be used to simulate how the bridge will respond to wind loads, traffic, or even an earthquake. (Abaqus tutorial)

Abaqus CAE is an integral part of the Abaqus suite. It acts as the pre-processing and post-processing environment. This means that Abaqus CAE allows engineers to:

  • Build models of the structures they want to analyze (like the bridge example).
  • Define the material properties of the different parts of the model (e.g., steel, concrete).
  • Set up the simulation conditions, such as the type of loading the structure will experience.
  • Visualize the results of the simulation to understand how the structure will deform or stress under those conditions.

In simpler terms, Abaqus CAE is the user-friendly interface you use to work with Abaqus. It’s where you prepare your questions (building the model and defining conditions) and then analyze the answers (visualizing the results).

Abaqus Modules Video Tutorial

A full Abaqus environment, Abaqus/CAE offers a straightforward, consistent user interface for creating, submitting, tracking, and assessing the results of Standard and Explicit simulations. Each module defines a logical step in the modeling process, such as specifying the geometry, defining the properties of the materials, and creating a mesh. Building the model used by Abaqus/CAE to produce the input file you give to the Standard or Explicit analysis product happens as you progress through the modules. The analysis tool performs the analysis, provides data to Abaqus/CAE so you can keep track of the job’s development, and creates an output database. Here, in the below training videos, you can get enough information about the modules and start simulating in this software.

Users ask these questions

When you search for the Abaqus tutorial, you encounter questions that users ask; some are common questions such as “What is the Abaqus unit system?” and some are specific. So, we decided to help the users and answered a few of them which you can see them below:

I. Substituting a 3D FEA problem to axisymmetric model

Q: Hello, everyone. How can an axisymmetric analysis of the identical problem replace a three-dimensional FE analysis of a threaded screw (inserted into a material with an insertion torque)? If you have any good references, please share them with us. Best wishes.

A: Hello,

It’s impossible to substitute a 3D threaded screw with an axisymmetric model. Because its geometry won’t allow us. I mean, the threads of the screw are not symmetric.

Best regards. 

II. Friction

Q: Should I put friction in any contact in my analysis? When can I use the “Frictionless” option in my analysis? How much value the friction coefficient should have?

A: In general, do not define any friction in contacts unless necessary. However, in a few cases, a simulation with high friction value will converge better. The ABAQUS/Standard will automatically use the asymmetric matrix storage if any friction value becomes greater than 0.2.

III. Saving node coordinates in a file

Q: when I query some coordinate points in Abaqus (through Tools -> Query), they normally appear in the message area. It is not saved in Abaqus’.rpy or.jnl files. Is there a way to record the coordinate points and then automate the process later with scripting? Based on a nonlinear tool path for AM, I want to define and activate a set of elements for thermal analysis. Query is currently the only way to obtain the coordinates. I’m searching for ways to automate it with scripting, but the query choices in Abaqus aren’t saved in.rpy or.jnl files.

A: Hello,

To save the coordinates of the nodes, you simply should select a variable named “COORD” from the Field Output (see figure 1). Then, you can get a report from it in the Visualization module after you run the job, and the coordinates will be saved in a file with extension “.rpt” (see figures 2 and 3).

IV. Meshing and analyzing a model

Q: I’m creating a model of a structure built of stone arrangements. Because the number of instances is so large, meshing and analyzing the assembly as a 3D deformable body fails due to my computer’s physical memory limit of 64 GB. Is there a way to test the stability of these blocks without having to mesh them?

A: Hi,

It’s not possible to do this without meshing. However, I recommend using the Submodeling technique. Analyze your model with less mesh and larger meshes. Find the critical sections, then use the Submodeling technique.

Also, I have some recommendations to speed up your simulation:

  • Use mass scaling if you are using the “Dynamic, Explicit” step.
  • If your model is quasi-static, increase the mass artificially.
  • You can change the time period and the size of the meshes as well.

You can refer to the links below to acquire more information. It’s worth a look.
