Detailed Description

Simple isotropic damage based model for 2d interface elements.

In 2d, the interface elements are used to model contact layer between element edges. The generalized strain vector contains two relative displacements (in normal and shear direction). The generalized stress vector contains corresponding tractions in normal and tangent direction.

The behaviour of the model is elastic, described by normal and shear stiffness components. Isotropic damage is initiated when the stress reaches the tensile strength. Damage evolution is governed by normal component of generalized strain vector (normal relative displacement) by an exponential softening law.

Member Function Documentation

int oofem::IntMatBilinearCZJansson::checkConsistency ( )
protectedvirtual

Allows programmer to test some internal data, before computation begins.

For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns
Nonzero if receiver is consistent.

virtual MaterialStatus* oofem::IntMatBilinearCZJansson::CreateStatus ( GaussPoint gp) const
inlinevirtual

Creates new copy of associated status and inserts it into given integration point.

Parameters
gpIntegration point where newly created status will be stored.
Returns
Reference to new status.
