This class implements a Fixed Crack Model for fracture (after initiation the crack directions cannot rotate).
After the onset of cracking, the cracks can still transfer tractions (i.e. cohesive crack approach) in both normal and shear directions. Cracks can develop only in mutually perpendicular directions. In elastic state this model is isotropic. This is class is purely abstract, it can be used only in the derived classes (e.g. ConcreteFCM)

Method for computing plane strain stiffness matrix of receiver.
Default implementation computes 3d stiffness matrix using give3dMaterialStiffnessMatrix and reduces it to plane strain stiffness using reduce method described above. However, this reduction is quite time consuming and if it is possible, it is recommended to overload this method and provide direct method for computing particular stiffness matrix. Note: as already described, if zero strain component is imposed (Plane strain, ..) this condition must be taken into account in geometrical relations, and corresponding component has to be included in reduced vector. (So plane strain conditions are , but relations for and are included).

Computes the real stress vector for given total strain and integration point.
The total strain is defined as strain computed directly from displacement field at given time. The stress independent parts (temperature, eigenstrains) are subtracted in constitutive driver. The service should use previously reached equilibrium history variables. Also it should update temporary history variables in status according to newly reached state. The temporary history variables are moved into equilibrium ones after global structure equilibrium has been reached by iteration process.
answer | Stress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress. |
gp | Integration point. |
