DEFINITION
ANISO specifies the various Hill’s anisotropic yield function.
REMARKS
When Hill’s quadratic (Polycrystal Plasticity) anisotropy yield function is selected (YieldType=4), texture information (crystal type, texture type) should be defined in Material dialog. At each material point of an object, orientation distribution functions will be evaluated as explained in keyword TXTODF. Applicable object types: Plastic, Elastoplastic, Note: Anisotropy is not available in “Torsion” mode in 2D.
