Numerical simulations have become essential in engineering and manufacturing processes
involving plasticity. The reliability and effectiveness of the simulations depend strongly on …

An inverse analysis methodology for determining the parameters of plastic constitutive
models is proposed. This involves the identification of the yield criterion and work-hardening …

This paper scrutinizes in detail the synergy between physical and virtual testing of the
mechanical response of sheet metal. In this context, physical testing refers to the usage of …

This article is a review regarding recently developed inverse strategies coupled with finite
element simulations for the identification of the parameters of constitutive laws that describe …

This paper presents an experimental and numerical study of the mechanical behaviour of
SAE 1045 steel sheet specimens during the conventional tensile test. Due to the complex …

The aim of this paper is the design of a quantitative indicator able to distinguish, rate and
rank different mechanical tests used to characterize the material behavior of sheet metals …

The main goal of this work is to design virtually a heterogeneous test, with appropriate
specimen shape and boundary conditions, which leads to an inhomogeneous strain field …

The main focus of the present work is the development of a global procedure for a complete
characterization of sheet metal behavior, including anisotropy, evolution of hardening and …

Calibration of hardening and partly viscoplastic parameters of the previously published
material model was the primary concern of this paper. The method used for identification of …

A phenomenological model is presented to describe the mechanical behaviour for metals
and alloys over a large range of strain rates. It is an elasto-plastic model with a strain rate …
