3D Hashin failure criteria in Abaqus
Damage initiation by Abaqus Hashin criterion
3D Hashin Failure criterion is not supported in Abaqus for solid elements. The Hashin damage initiation criterion must be used with elements with a plane stress formulation, which include plane stress, shell, continuum shell, and membrane elements. so it is not used for 3D solid elements. It is often necessary to use 3D solid elements (For example C3D8R) in simulating the damage of FRP composite materials with an explicit solver. So what is the solution?
The Abaqus anisotropic damage model for unidirectional fiber-reinforced composite is based on the work of Matzenmiller et al. (1995), Hashin and Rotem (1973), Hashin (1980), and Camanho and Davila (2002).
Four different modes of failure are considered:
- fiber rupture in tension;
- fiber buckling and kinking in compression;
- matrix cracking under transverse tension and shearing; and
- matrix crushing under transverse compression and shearing.
Damage evolution for fiber-reinforced composites in Abaqus
it is based on energy dissipation during the damage process and is linear. in the following table, you can find the differences between Abaqus built-in Hashin model and the 3D Hashin VUMAT subroutine.

|Damage Initiation||Hashin and Rotem (1973), Hashin (1980)||Hashin (1980) and Maximum stress criteria|
|Damage Evolution||Linear||Exponential (based on Linde (2004))|
|Solver||Standard & Explicit||Explicit|
