Detailed Description

Material damage model for transversely orthotropic material. Fixed cracks are induced in principal material coordinates, always perpendicular to material axis. Six cracking modes are implemented in three orthogonal directions - three for tension/compression failure and three for shear failure. Material orientation can be specified on each element with "lmcs" keyword, otherwise global material orientation is assumed.

Evolution of cracks is determined separately in compression and tension. Linear softening is assumed (can be easily changed to exponential but requires then inner iterations)

For derivation of the model see the book Bazant and Planas, Fracture and Size Effect in Concrete and Other Quasibrittle Materials, pp.236 or article Bazant and Oh: Crack band theory for fracture of concrete, Materials and Structures, 1983.

The model is aimed for 3D problems but extension for 1D truss works. In this particular case, only the first array component is used in all involved variables.

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.

Parameters

answer	Stress vector in reduced form. For large deformations it is treated as the second Piola-Kirchoff stress.
gp	Integration point.
reducedStrain	Strain vector in reduced form. For large deformations it is treated as the Green-Lagrange strain.
tStep	Current time step (most models are able to respond only when tStep is current time step).

Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record. Note that initializeFrom may be called mutiple times.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.
priority	Priority of the input record. This is used to determine the order of initialization

Reimplemented from oofem::FEMComponent.

◆ afterIter

int oofem::CompoDamageMat::afterIter = 0

Optional parameter determining after how many iterations within the time step the damage is calculated. This is important for stress evaluation which is unequilibrated in the beginning. Variables strainAtMaxStress, initDamageStress, maxStrainAtZeroStress are evaluated afterIter.
