Abaqus Hashin damage model for 3D composites - Basics, Relations, Examples using VUMAT subroutine

This tutorial provides instructions on simulating damage in 3D continuum composite materials within ABAQUS. Since ABAQUS lacks a built-in material model for 3D composites, users must create a VUMAT subroutine to simulate both the initiation and progression of damage in these materials. In this video, the Hashin criterion, a widely utilized method for detecting failure, is employed. Notably, the subroutine incorporates a gradual progression of damage using the energy method. This intricate subroutine is applicable to both static and dynamic problems. 0:00- Intro 2:02- The Use of VUMAT subroutine 2:53- When we need use 3D continuum elements for composites? 3:44- Equations of 3D continuum Elasticity 4:52- 3D continuum Hashin damage theory 7:46- VUMAT subroutine for damage model 10:52- An example in impact analysis 16:39- Damage model in a plate with hole (Static analysis) You can have access to the full tutorial along with example files via this link: https://caeassistant.com/product/3d-continuum-hashin-progressive-damage-for-composite-materials-in-abaqus-vumat-subroutine-1/
