USDFLD
Additive Manufacturing or 3D Printing Abaqus simulation
3D printing is a process of creating three-dimensional objects by layering materials, such as plastic or metal, based on a digital design. 3D printing simulation involves using software to predict and optimize the printing process, allowing for more efficient and accurate production. 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".
Additive manufacturing simulation with Abaqus subroutine & python | 3D printing Python
3D printing is a technique for creating three-dimensional objects by layering materials such as plastic or metal based on a digital design. 3D printing simulation involves the use of software to predict and enhance the printing process, resulting in more efficient and precise production. This training package is based on the use of subroutines and Python scripting. Following an introduction to the 3D printing process, this method with all its details is explained. Two workshops are then conducted for this method. The first workshop covers 3D printing simulation of a gear with a uniform cross-section, while the second workshop covers a shaft with a non-uniform cross-section.
Composite simulation for experts-Part-2
Pay attention to the syllabus and availability file details. some of the packages are fully available and some of them are partially available. If this is partially available it takes at least two months to be completely available.
If you are a researcher, student, university professor, or Engineer in the company in the field of composite materials, this training package in simulating these materials in Abaqus software is the best selection. This training package is the second part of the composite for expert package and is focusing on the Simulation of woven composite damage in Abaqus, Composite Fatigue Simulation, Analysis of Composite pressure vessel with Semi-Geodesic winding, Simulation of composite Hashin damage in 3d continuum element (UMAT-VUMAT-USDFLD), and Abaqus composite modeling of Woven & Unidirectional + RVE method.
Composite pressure vessel analysis with Semi-Geodesic winding
Nowadays, pressure vessels are produced using various methods, one of which is filament winding. This package teaches the simulation of composite pressure vessels produced using the filament winding method. Filament winding itself has different methods, and one of the most widely used winding methods for producing composite vessels is the semi-geodesic filament winding method. In this package, first, the semi-geodesic method is described. Then, the simulation of a semi-geodesic vessel is performed using a Python script. Additionally, a UMAT subroutine is used to simulate the failure of composite materials used in the vessel.
Simulation of composite Hashin damage in 3d continuum element in Abaqus (UMAT-VUMAT-USDFLD)
In this training package, the 3D continuum HASHIN damage initiation model is prepared via three subroutines (USDFLD, UMAT and VUMAT).This training package teach you subroutines line-by-line. It should be noted that after damage initiation, failure occurs suddenly and in the form of a reduction in properties in the model. The HASHIN theory for this package is based on Kermanidis article titled” FINITE ELEMENT MODELING OF DAMAGE ACCUMULATION IN BOLTED COMPOSITE JOINTS UNDER INCREMENTAL TENSILE LOADING “.
Composite simulation for experts-Part-1
If you are a graduate or Ph.D. student, if you are a university professor or an expert engineer in the industry who deals with simulation software, you are definitely familiar with the limitations of this software in defining the material properties, loading or meshing, interaction properties, and etc. You have certainly tried to define the properties of materials based on advanced fracture theories in finite element software and are familiar with their limitations and problems.
Now, here is your solution. Start writing subroutines in finite element software and overcome the limitations. With the tutorials in the Golden Package, you will learn how to write 8 subroutines in Abaqus software professionally.
Simulation of composite Puck damage in 3d continuum element in Abaqus (UMAT-USDFLD-VUMAT)
The Puck criterion is an essential damage model for composite materials, considering both fiber and matrix failures simultaneously. It provides a practical way to predict the onset of damage in composites under various loading conditions. This training package is focused on simulating composite PUCK damage in 3D continuum elements using UMAT, VUMAT, and USDFLD subroutines in Abaqus. It covers different types of failure in composites, including fiber failure, matrix cracking, delamination, and interfacial failure, as well as criteria for predicting failure modes in composites that are dependent or not dependent on each other, such as the Tsai-Wu and Tsai-Hill criterion, respectively. Additionally, the package covers composites' most commonly used damage criteria, including the Puck criterion. The package provides step-by-step guidance on simulating composite Puck damage using each of the subroutines mentioned above in Abaqus.
Introduction to USDFLD and VUSDFLD Subroutine
In this usable tutorial, the material properties can change to an arbitrary dependent variable. One of the most important advantages of this subroutine is simplicity and applicability. Various and high usage examples are unique characteristics of the training package.
This training package includes 5 workshops that help you to fully learn how to use USDFLD and VUSDFLD subroutines in Abaqus software. By means of these subroutines, you will have expertise redefine field variables at a material point by the solution dependence of standard and explicit, respectively.
