A severe obstacle for the routine use of crystal plasticity models is the effort associated with
determining their constitutive parameters. Obtaining these parameters usually requires time …

Discontinuous dynamic recrystallization (dDRX) is considered an effective way to obtain fine
grain microstructures during hot working of materials with low-to-medium stacking fault …

An internal-state-variable based self-consistent constitutive model was proposed for unified
prediction of flow stress and microstructure evolution during hot working of wrought two …

Nowadays, everybody agrees on the fact that good multiaxial constitutive equations are
needed in order to study the stress-strain response of materials. After many studies, a …

This paper focuses on an inverse problem involving a commonly used material model in
structural steel applications—the Voce-Chaboche model. In particular, the paper proposes …

Finite element model updating (FEMU) is an advanced inverse parameter identification
method capable of identifying multiple parameters in a material model through one or a few …

Microstructural evolution, which is governed by temperature, strain and strain rate during hot
forging, is a key factor influencing mechanical properties. Understanding the microstructural …

A complex constitutive relation is identified using inverse modeling with the nominal
mechanical response as sole experimental input. The methodology is illustrated for a …

The aim of this study is to investigate the mechanical behaviour of a fluoro-elastomer.
Several tension and compression cyclic loading and relaxation tests have been performed …

A set of constitutive equations coupling microstructure evolution have been developed for
hot working of a TA15 titanium alloy. Physically-based microstructure models were …
