LaRCCriterion#

class ansys.dpf.composites.failure_criteria.LaRCCriterion(*, lft=True, lfc=True, lmt=True, lmc=True, dim=2, wf_lft=1.0, wf_lfc=1.0, wf_lmt=1.0, wf_lmc=1.0)#

Defines the LaRC failure criterion for UD reinforced materials.

Parameters:

lft (bool, default: True) – Whether to activate the failure evaluation regarding tension in fiber direction.
lfc (bool, default: True) – Whether to activate the failure evaluation regarding compression in fiber direction.
lmt (bool, default: True) – Whether to activate the failure evaluation of the matrix due to tension.
lmc (bool, default: True) – Whether to activate the failure evaluation of the matrix due to compression.
dim (int, default: 2) – Whether the 2D or 3D formulation of the criterion is used. 2D is equivalent to LaRC03, and 3D is equivalent to LaRC04.
wf_lft (float, default: 1.0) – Weighting factor of fiber failure due to tension (lft).
wf_lfc (float, default: 1.0) – Weighting factor of fiber failure due to compression (lfc).
wf_lmt (float, default: 1.0) – Weighting factor of matrix failure due to tension (lmt).
wf_lmc (float, default: 1.0) – Weighting factor of matrix failure due to compression (lmc).
