Abstract:
Abaqus software has been used in Trelleborg AVS since 1980s. In addition to general simulation capabilities, the software provides users with more functions to solve complex engineering issues, such as user subroutines. In a large deformation with non-linear materials involved, user subroutine VUSDFLD could be used for crack propagations in explicit simulations. This work describes a procedure to introduce subroutine VUSDFLD in explicit simulations for rubber antivibration applications. Since this routine provides access to material point quantities, a user can define any new user-defined field to evaluate the material damage, such as life prediction of rubber components. The following main points are presented to define the user routine:
Assigning predefined fields
Keeping data in large arrays
Output controls
Stress/strain data in a 1D array and a 2D array
Element deletion for damage simulation
I am really appreciate the support I received from SIMULIA's Stuart Nixon.
