The behavior of materials under high strain rates is pivotal to their deformation during
machining processes. This research focuses on numerical modeling of the dynamic …

Because the design of most products incorporates numerical analysis such as the finite
element method, these days, accurate determination of dynamic material model parameters …

When a material is deformed at high speed, it is well known that the flow stress is highly
dependent on the strain rate and temperature. So, many studies of the stress-strain …

For numerical simulations of rapid forming processes the most used constitutive equations
are based on the Johnson-Cook (JC) law and on the Zerilli-Armstrong (ZA) one. Starting …

The analysis and optimization of rapid or severe material forming process, where high
gradients of plastic deformations, strain rates and temperatures are reached during the …

For non-conventional or rapid forming processes important gradients of the plastic strain and
strain rate can be reached, especially for severe loadings or complex deformation paths …

Les procédés de mise en forme de tôles minces sont très largement répandus dans
l'industrie. Néanmoins, l'utilisation de ces procédés est limitée par le niveau de formabilité …

The complex loading paths of non-conventional or rapid forging processes, especially as
regards the important gradients of the plastic strain and strain rate characterizing the …

In the field of material behavior corresponding to high strain rates the most used constitutive
laws are Johnson-Cook (JC) and Zerilli-Armstrong (ZA). Many scientific studies use these …

This research paper focus on the experimental design and analytical/numerical analysis of a
