Member Data Documentation

fracture_toughness

P const& MaterialLib::Fracture::CohesiveZoneModeI::MaterialPropertiesParameters::fracture_toughness

Fracture toughness/critical energy release rate given in of stress times lengths.

The fracture toughness \(G_{c}\) denotes the total energy dissipation to resist a fracture. Graphically, its value equals to the total area below the bilinear curve.

normal_stiffness

P const& MaterialLib::Fracture::CohesiveZoneModeI::MaterialPropertiesParameters::normal_stiffness

Normal stiffness given in units of stress per length.

Definition at line 60 of file CohesiveZoneModeI.h.

peak_normal_traction

P const& MaterialLib::Fracture::CohesiveZoneModeI::MaterialPropertiesParameters::peak_normal_traction

Peak normal traction given in units of stress per length.

The peak tensile normal traction \(t_{n,p}\) denotes the maximum normal traction in the linear elastic phase. The corresponding normal fracture opening \(w_{n,p}\) then comes out according to the Hooke's law. With the proceeding of delamination over this opening threshold, damage takes place so that the bearing loading of the material linearly drops down.

shear_stiffness

P const& MaterialLib::Fracture::CohesiveZoneModeI::MaterialPropertiesParameters::shear_stiffness

Shear stiffness given in units of stress per length.
