Detailed Description

This class implements an isotropic elastoplastic material with Mises yield condition, associated flow rule and linear isotropic hardening.

It differs from other similar materials (such as J2Mat) by implementation - here we use the radial return, which is the most efficient algorithm for this specific model. Also, an extension to large strain will be available.

The model also exemplifies how to implement non-3d material modes, in this case 1D, by overloading the default implementations that iterates over the 3D method.

overridevirtual

Default implementation relies on giveRealStressVector_StressControl.

Note: : One should obtain the same answer using the iterations in the default implementation (this is verified for this model).

◆ initializeFrom()

void oofem::MisesMat::initializeFrom ( InputRecord & ir )

overridevirtual

Initializes receiver according to object description stored in input record. This function is called immediately after creating object using constructor. 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.
