HashinCriterion

class ansys.dpf.composites.failure_criteria.HashinCriterion(*, hf=True, hm=True, hd=False, dim=2, wf_hf=1.0, wf_hm=1.0, wf_hd=1.0)

Defines the Hashin failure criterion for UD reinforced materials.

Parameters:

• hf (bool, default: True) – Whether to activate the failure evaluation regarding fiber failure.

• hm (bool, default: True) – Whether to activate the failure evaluation regarding matrix failure.

• hd (bool, default: False) – Whether to activate the failure evaluation regarding delamination if dim is equal to 3.

• dim (int, default: 2) – Whether the 2D or 3D formulation of the criterion is used. The latter one also supports the failure mode delamination.

• wf_hf (float, default: 1.0) – Weighting factor of the fiber failure (hf) mode.

• wf_hm (float, default: 1.0) – Weighting factor of the matrix failure (hm) mode.

• wf_hd (float, default: 1.0) – Weighting factor of the delamination (hd) mode.
