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.
