Evaluation on Flexibility of Phenomenological Hardening Law for Automotive Sheet Metals
Metals, 2022 Constitutive modeling of sheet metals involves building a system of equations governing the material behavior under multi-axial stress states. In general, these equations require a hardening law that describes the stress-strain relationship.

Strain Hardening in Polymer Glasses: Limitations of Network Models [PDF]
, 2007 Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While traditional entropic network models can be fit to the total stress, their underlying assumptions are inconsistent with simulation results.

Mg-3Al-1Zn alloy deformed along different strain paths: Role of latent hardening
Journal of Magnesium and Alloys, 2023 The mechanical properties of magnesium alloy AZ31 were investigated experimentally with visco-plastic self-consistent modeling. Tension, compression and plane strain compression (PSC) tests were performed along 3 directions of a hot rolled plate, and the

Gross plastic deformation of axisymmetric pressure vessel heads [PDF]
, 2006 The gross plastic deformation and associated plastic loads of four axisymmetric torispherical pressure vessels are determined by two criteria of plastic collapse: the ASME twice elastic slope (TES) criterion and the recently proposed plastic work ...
