Advanced UMAT Subroutine (VUMAT Subroutine)

This training package helps Abaqus users to prepare complex UMAT and VUMAT subroutines. This training package is suitable for those who are familiar with subroutine or want to learn UMAT/VUMAT subroutine Professionally. Equations for computational plasticity based on kinematic stiffness are also discussed. In addition, metal damage has been implemented based on Johnson Cook's model. Watch Demo

Composite Fatigue Simulation with Subroutine in ABAQUS Part1

The composite fatigue training package completely teaches how to simulate and analyze a fatigue composite model with the help of UMAT Subroutine in Abaqus software. In this training package, we have provided all the files needed for your training, including articles, theories, how to write subroutines, and software settings.

3D continuum HASHIN progressive Damage for composite materials in ABAQUS (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, this subroutine includes gradual progressive damage based on the energy method. This complex subroutine could be used for static and dynamic problems.

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.

UMAT Subroutine (VUMAT Subroutine) introduction


This package is usable when material model is not available in ABAQUS software. If you follow this tutorial package, included standard and explicit solver, you will have ability to write, debug and verify your subroutine based on customized material to use this in complex structures. These lectures are introduction to write advanced UMAT and VUMAT subroutines in hyper elastic Martials, Composites and Metal and so on. Watch Demo

Implementation of Lemaitre Damage model with VUMAT subroutine

The Lemaitre damage model is now widely used to deal with coupled damage analyses for various mechanical applications. In this package, Firstly, we try to introduce the Lemaitre damage model including damage mechanics and formulation of the Lemaitre damage model. Then, writing the Lemaitre subroutine is reached step by sep. To do this job, the flowchart of the subroutine, Writing the subroutine line by line, implementation of the subroutine in one element and verification is done. In the last chapter, we implement this subroutine in a complex problem, the upsetting process.   . Watch Demo
