Computational Modeling of Steel Plate Shear Wall (SPSW) Behavior

320.0

This course equips engineers with the tools to design and analyze Steel Plate Shear Walls (SPSW) and Reinforced Concrete Shear Walls (RCSW) subjected to explosive loads. Traditional Finite Element (FE) simulation is time-consuming and requires numerous samples for accurate results. This package offers a more efficient approach using Artificial Intelligence (AI) models trained on FEA data. You'll learn to develop FE models of SPSW and RCSW in ABAQUS software, considering material properties, interactions, and boundary conditions. The Taguchi method optimizes the number of samples needed for FE analysis, and this method is used with SPSS after explanation its concept.

We then delve into AI modeling using MATLAB. Explore various methods like regression, Machine Learning (ML), Deep Learning (DL), and ensemble models to predict the behavior of SPSW and RCSW under blast loads. Statistical analysis helps compare model accuracy. By combining FE analysis with AI models, you'll gain a powerful tool for designing blast-resistant structures while saving time and resources.

3D Simulation of Gurson-Tvergaard-Needleman (GTN) Damage Model

190.0
The GTN (Gurson-Tvergaard-Needleman) damage model is a robust continuum damage model used to simulate ductile fracture in materials. It accounts for porosity, a key damage parameter, to predict material behavior under various loading conditions. The model's benefits include comprehensive fracture analysis, accurate damage prediction, versatility, and enhanced simulation capabilities. Despite these advantages, implementing the GTN model in software like Abaqus (GTN model Abaqus) is challenging. It is due to the need for custom subroutines, such as VUMAT. However, writing the subroutine requires proficiency in Fortran programming and an understanding of finite element analysis. This project provides a detailed guide for using the VUMAT subroutine to define the GTN model in Abaqus. It addresses challenges like high computational costs and the need for extensive experimental data. The tutorial demonstrates the model's application in material design, failure analysis, structural integrity assessment, research and development, and manufacturing process simulation. By exploring stress distribution, nodal temperatures, and displacement fields, the project aims to enhance the understanding and predictive capabilities of the GTN damage model.

Simulation of an Ultrasonic Transducer (3D Ultrasonic Vibration Assisted Turning Tool)

190.0

Since the invention of ultrasonic vibration assisted turning, this process has been widely considered and investigated. The reason for this consideration is the unique features of this process which include reducing machining forces, reducing wear and friction, increasing the tool life, creating periodic cutting conditions, increasing the machinability of difficult-to-cut material, increasing the surface quality, creating a hierarchical structure (micro-nano textures) on the surface and so on. Different methods have hitherto been used to apply ultrasonic vibration to the tip of the tool during the turning process. In this research, a unique horn has been designed and constructed to convert linear vibrations of piezoelectrics to three-dimensional vibrations (longitudinal vibrations along the z-axis, bending vibrations around the x-axis, and bending vibrations around the y-axis). The advantage of this ultrasonic machining tool compared with other similar tools is that in most other tools it is only possible to apply one-dimensional (linear) and two-dimensional (elliptical) vibrations, while this tool can create three-dimensional vibrations. Additionally, since the nature of the designed horn can lead to the creation of three-dimensional vibrations, there is no need for piezoelectric half-rings (which are stimulated by a 180-phase difference) to create bending vibrations around the x and y axes. Reduction of costs as well as the simplicity of applying three-dimensional vibrations in this new method can play an important role in industrializing the process of three-dimensional ultrasonic vibration assisted turning.

In this example, how to model all the components of an ultrasonic transducer and its modal and harmonic analysis are taught in full detail.

Different Techniques for Meshing in Abaqus

180.0
(11)
This package introduces different meshing techniques in Abaqus. In finite element analysis, a mesh refers to the division of a physical domain into smaller, interconnected subdomains called elements. The purpose of meshing is to approximate the behavior of a continuous system by representing it as a collection of discrete elements. Meshing is of utmost importance in finite element analysis as it determines the accuracy and reliability of the numerical solution. Through this tutorial, initially, the mesh and related terms associated with meshing are declared. Abaqus mesh module and meshing process are introduced. Then, two different meshing methodologies: Top-down and Bottom-up with meshing techniques available for each one of them are completely explained. Some of the advanced meshing techniques and edit mesh toolset are also included. The consideration of mesh verification as the final step in the meshing process, along with its criteria, is undertaken. All the tips and theories determined in this tutorial are implemented in Abaqus/CAE as a workshop to mesh several parts. This package intends to take your ability to mesh different parts to a higher level.

Simulation of shape control by piezoelectric in Abaqus

290.0
(1)
Piezoelectricity refers to the accumulation of electric charge in certain solid materials due to mechanical pressure. This phenomenon, known as the piezoelectric effect, is reversible. Some materials exhibit direct piezoelectricity, which involves the internal production of electric charge through the application of mechanical force, while others exhibit the inverse piezoelectric effect. By harnessing piezoelectrics, it becomes possible to control the geometrical changes of objects in response to external forces. However, it is important to note that utilizing this property in all situations would not be cost-effective. Therefore, it is more practical to use piezoelectric structures selectively, specifically in special applications. One approach to determining the optimal placement of piezoelectric elements for controlling the geometric shape of various objects under internal or external forces involves utilizing the Abaqus and MATLAB software linkage. This software combination, along with optimization algorithms such as the particle swarm optimization algorithm, can be employed to achieve the desired objectives. By leveraging these tools and data, the primary goal of controlling object shape can be successfully accomplished. In this training package, you will learn about piezoelectric and piezoelectric modeling in Abaqus, the particle swarm optimization algorithm, linking Abaqus and MATLAB, and how to use these tools for shape control. Notice: Software files and A full PDF guideline (Problem description, theory, ...) are available; Videos are coming soon.

Techniques of simulating Large and Complex models in Abaqus

158.0
(1)
Sometimes, there is a need to simulate large or complex models in Abaqus, such as airplanes and cars. Generally, models with more than 5 million variables or take at least 12 hours to analyze are considered large. Processing such models requires a significant amount of time and energy, in addition to potential issues with modeling, loading, boundary conditions, and more. Therefore, it is necessary to find ways to simplify and accelerate the analysis of such models. In this training package, you will learn various methods to address these challenges. Dealing with large models typically involves simplifying the model, making efficient use of system resources, and minimizing CPU time. These techniques are explained in detail here. Additionally, you will be taught various techniques to aid in the management of large models, including submodeling, history output filtering, restart functionality, and parts and assemblies.
