class ansys.dpf.composites.failure_criteria.MaxStressCriterion(*, s1=True, s2=True, s3=False, s12=True, s13=False, s23=False, wf_s1=1.0, wf_s2=1.0, wf_s3=1.0, wf_s12=1.0, wf_s13=1.0, wf_s23=1.0)#

Defines the maximum stress failure criterion for orthotropic reinforced materials.

Parameters:
  • s1 (bool, default: True) – Whether to activate the failure evaluation regarding the stress in the material 1 direction.

  • s2 (bool, default: True) – Whether to activate the failure evaluation regarding the stress in the material 2 direction.

  • s3 (bool, default: False) – Whether to activate the failure evaluation regarding the stress in the material 3 direction (out-of-plane).

  • s12 (bool, default: True) – Whether to activate the failure evaluation regarding the in-plane shear stress s12.

  • s13 (bool, default: False) – Whether to activate the failure evaluation regarding the interlaminar shear stress s13.

  • s23 (bool, default: False) – Whether to activate the failure evaluation regarding the interlaminar shear stress s23.

  • wf_s1 (float, default: 1.0) – Weighting factor of the failure mode s1.

  • wf_s2 (float, default: 1.0) – Weighting factor of the failure mode s2.

  • wf_s3 (float, default: 1.0) – Weighting factor of the failure mode s3.

  • wf_s12 (float, default: 1.0) – Weighting factor of the failure mode s12.

  • wf_s13 (float, default: 1.0) – Weighting factor of the failure mode s13.

  • wf_s23 (float, default: 1.0) – Weighting factor of the failure mode s23.
