3D continuum Abaqus HASHIN progressive Damage for composite materials (VUMAT Subroutine)

 320.0
(10)
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.

Three workshops are presented so you can learn all these stuff in action: Simulation of welding between two plate with DFLUX subroutine, Simulation of Arc welding between two tube with DFLUX, and Simulation of different types of functional heat flux(Body-surface-Element) in plate with Johnson-cook plasticity with VDFLUX subroutine(Thermomechanical Analysis).

Introduction to UEL Subroutine in ABAQUS

 210.0
(8)
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. This package contains two workshops: writing a UEL subroutine for a planar beam element with nonlinear section behavior and writing a UEL subroutine for a beam element with specific boundary conditions and loading.
