Experimental study of internal variable evolution in SS304L, at multiple rates and temperatures

Article Abstract:

A series of reverse yield experiments were performed to directly calculate the evolution of alpha and kappa in 304L stainless steel (SS304L) over large ranges of strain rates and temperatures. The capability of the model to simulate the behavior of SS304L under various loading conditions across a wide range of strain rates and temperatures was also studied. Results indicate that the material exhibited inelastic behavior immediately on changing the straining direction.

Representing the effect of crystallographic texture on the anisotropic performance behaviour of rolled aluminum plate

Article Abstract:

In this article measuring and modeling the anisotropy of rolled aluminum plate in relation to processing-induced crystallographic texture is discussed. Simulation analysis predicted anisotropy in both the back-extrapolated yield strength and the elastic/elastic-plastic transition of the AA7075 plate material.

Anisotropic nonlinear kinematic hardening rule parameters from reversed proportional axial-torsional cycling

Article Abstract:

This article presents a methodology to determine Armstrong-Frederick type kinematic hardening rule parameters for analysis of cyclic plasticity and viscoplasticity of metals. Data show that axial-torsional cycling responses of type 304 tubular stainless steel specimens improved using this rule.
