The use of thermoplastics in the automotive industry is continuously increasing. Design of
parts require the characterization and numerical modelling of thermo-mechanical behaviour …

A phenomenological finite strain non-associated elastoviscoplastic model coupled with
damage is proposed in order to simulate the behaviour of a 20% mineral filled semi …

Abstract System ringing in load measurement during dynamic tests is investigated with a
second order system consisting of a mass, a spring and a damper. According to the analysis …

The mechanical characterization of a polymer gel used as reference backing material for
blunt ballistic impact interpretation is performed at room temperature from quasi-static (0.002 …

The identification of viscoplastic material parameters is addressed using a new powerful
method: the virtual fields method (VFM). Contrary to classical procedures that are statically …

This paper deals with a viscoelastic–viscoplastic model for semi-crystalline polymers in
crash applications. A polymer behaviour model is implemented in the commercial PAM …

This study is devoted to the necking phenomenon and to the kinematic aspects associated
with this plastic instability. The material studied is a High Density PolyEthylene deformed in …

Nowadays characterization of the strain-rate dependence of materials becomes
indispensable in crashworthiness design of structures (ie car-bodies, ships) with CAE …

The ongoing pursuit of quality improvement and cost reduction in metal forming operations
has instigated intense research on both material modelling and identification of constitutive …

This study proposes a constitutive model of viscous behaviour of short-fibre reinforced
composites (SFRC) with complex distributions of fibre orientations and for a wide range of …
