FaceSheetWrinklingCriterion#

class ansys.dpf.composites.failure_criteria.FaceSheetWrinklingCriterion(*, homogeneous_core_coeff=0.5, honeycomb_core_coeff=0.33, wf=1.0)#

Defines the face sheet wrinkling criterion for sandwiches (laminate with cores).

Parameters:
  • homogeneous_core_coeff (float, default: 0.5) – Wrinkling coefficient (reduction factor) for homogeneous core materials.

  • honeycomb_core_coeff (float, default: 0.33) – Wrinkling coefficient (reduction factor) for honeycombs. The default is 0.33.

  • wf (float, default: 1.0) – Weighting factor of the failure mode (wb or wt). The default is 0.5.
