Simulation of cohesive fatigue in Abaqus with subroutine
Simulation of woven composite fatigue in Abaqus
The training package focuses on simulating woven composite fatigue using Abaqus software and the modified Hashin fatigue damage model based on the article titled "Life prediction of woven CFRP structure subject to static and fatigue loading ". Woven composites have high strength and stiffness-to-weight ratios, but the interlacing pattern can affect stress distribution and damage mechanisms, making fatigue analysis crucial. The package includes four lessons covering different types of composite fatigue models, material characterization, generalization of the failure model, and the implementation of the UMAT subroutine. Two workshops provide hands-on experience in implementing the UMAT subroutine on one element in cyclic tension and a complex model. Fatigue analysis predicts material behavior under cyclic loading and helps design safe and reliable structures.

Watch DemoSimulation of SMA in Abaqus with UMAT
Shape-memory alloys (SMAs) have the ability to recover their original shape, thanks to the shape-memory effect and superelasticity. These unique characteristics have led to the broad usage of SMAs in engineering and medical applications. Simulations offer cost-effective methods for analyzing SMAs’ behavior, ultimately enhancing their reliability and performance. Consequently, researchers frequently employ simulations to investigate SMA-based systems. This educational package begins by exploring the fundamentals of SMA wires, presenting their various types and specific capabilities. It then provides the necessary constitutive equations to describe the behavior of SMAs in simulation. The package includes a flowchart and a step-by-step guide for writing a subroutine to model SMAs in Abaqus. Users will also discover a workshop that uses Abaqus to simulate the superelasticity effect in SMA wires. This workshop not only offers guidance on the simulation and the implementation of the subroutine, but also compares the result with an analytical solution for verification.

Professional Package
As a professional Abaqus user, you have probably faced cases where you have to move meshes and elements during analysis. For example, there is such a need in the wearing process. In addition, to define the properties of materials based on advanced theories of elasticity or plasticity, you need programming within the software. Sometimes you may need to model different types of cohesive or many types of composite materials based on various methods of composite damage. In all these cases, be sure that the professional package will answer you. This package is designed and prepared for you who are professionals and work on the edge of knowledge topics in the field of mechanical engineering and damage mechanics.
Sometimes you may need to use user-defined elements and change element configuration based on theories that you are using; for instance, it is needed to add more integration points in elements. In this case, you can use the UEL package in the “Professional Package”.

3D continuum Abaqus HASHIN progressive Damage for composite materials (VUMAT Subroutine)
This tutorial teaches how to simulate damage in 3d continuum composite materials in ABAQUS. As you know, Abaqus does not have any material model for 3d composite materials. So, the user needs to write a customized subroutine to simulate damage initiation and progressive damage for composite materials in ABAQUS. In this package, one of the most practical damage initiation criteria (Hashin) is used to detect failure. 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.

Introduction to UEL Subroutine in ABAQUS
UEL stands for User-defined Elements. When you have a finite element analysis that requires an element type that doesn't exist in the Abaqus element library, you must write a UEL subroutine. Or, when you want to define various element shape functions, the UEL would be the best choice. This subroutine is one of the most sophisticated in the Abaqus and is intended for advanced users. With this tutorial package, you can become an advanced user and learn how to write such a complex subroutine.

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".
