VonMisesCriterion

class ansys.dpf.composites.failure_criteria.VonMisesCriterion(*, vme=True, vms=True, wf_vme=1.0, wf_vms=1.0, eval_ins=False)

Defines the von Mises criterion for isotropic materials.

Parameters:

• vme (bool, default: True) – Whether to activate the von Mises strain criterion.

• vms (bool, default: True) – Whether to activate the von Mises stress criterion.

• wf_vme (float, default: 1.0) – Weighting factor of the strain criterion (vme).

• wf_vms (float, default: 1.0) – Weighting factor of the stress criterion (vms).

• eval_ins (bool, default: False) – Whether to consider interlaminar normal stresses (s3) and compute them for layered shells.
