Plasticity in solids is dependent on microstructural history, temperature, and loading rate, sample-dependent knowledge of yield points structural materials adds reliability to mechanical behavior. Yielding commonly measured through controlled testing, ways that either distinguish elastic (stress) from total deformation measurements or identify plastic slip contributions. In this paper, we show...

A new phenomenological strain hardening function is proposed to describe the behavior of metallic materials. The based on a simplification an earlier established self and latent crystal plasticity approach. contains only four parameters, which can be readily obtained using efficient numerical technique by fitting experimental curve. Several applications different materials are presented good ag...

A model for the elastic-viscoplastic response of metallic single crystals is developed on the basis of the modern finite-deformation theory of plasticity combined with considerations of material symmetry. This is proposed as an alternative to conventional crystal plasticity theory, based on a decomposition of the plastic deformation rate into a superposition of slips on active slip systems. A s...
