Introduction

This damage initiation law predicts failure in transversely isotropic materials. Because it deals with a specific material type, this law is only appropriate for TransIsoSoftening1 and 2 materials.

The following table lists the input properties for this initiation law

Property Description Units Default
sigmacA Critical stress for failure in the axial direction pressure units infinite
taucA Critical shear stress for failure due to axial shear stress with failure parallel to the axial direction pressure units infinite
taucT Critical shear stress for failure due to axial shear stress with failure through the axial direction pressure units infinite
sigmac Critical transverse tensile strength for tensile failure in the isotropic plane (output as sigmacT) pressure units infinite
tauc Critical transverse shear stress for shear failure n the isotropic plane (output as taucRS) pressure units infinite
