Abstract
In this contribution a review of several aspects of formulating yield surfaces and plastic potentials withing the framework of isotropic tensor functions is presented. Assuming transversal isotropic material symmetry, as e.g. suitable for a wide range of fiber reinforced composites, general formulations for the yield surface and plastic potential are given in terms of the full quadratic form. Procedures to relate the set of parameters arising from the quadratic form to the material behaviour are outlined. Thereby, emphasis is put on the implementation of constitutive modelling assumptions that lead to specific formulations, obtained from the quadratic form. The considered modelling assumptions are: independence of the yield surface from longitudinal (fiber) stress and independence of hydrostatic stress, as well as incompressibility and inextensibility for the plastic potential.
