For metallic materials, standard uniaxial tensile tests with round bar specimens or flat
specimens only provide accurate equivalent stress–strain curve before diffuse necking …

We focus on the importance of accurately describing the flow behaviors of metallic materials
to be cold formed; we refer to several valuable examples. We review the typical …

The static elastoplastic characterization of metals consists of the determination, by way of
experimental tensile tests, of the curve expressing the equivalent von Mises stress as a …

Cavitation erosion during the incubation period was investigated via pitting tests conducted
on three different materials: an Aluminum alloy, a Nickel Aluminum Bronze alloy and a …

The relationship between von Mises equivalent stress σ¯ and equivalent plastic strain
ε¯(PEEQ), termed as von Mises stress-strain, plays an important role in numerical …

All damage and failure models, describing either the evolution of microvoids, the
development of shear bands or local rupture, rely on the knowledge of the hardening …

The triaxiality of the stress state is known to greatly influence the amount of plastic strain
which a material may undergo before ductile failure occurs. During tensile load histories, the …

The strain hardening behavior of structural steels is of significant importance for the
elastoplastic response prediction and the collapse resistant evaluation of steel components …

Poly (ether-ether-ketone)(PEEK) has been used as a load bearing orthopaedic implant
material with clinical success. All of the orthopaedic applications contain stress …

The development of ductile damage, that occurs beyond the point of necking in a tensile test,
can be difficult to quantify. An experimental methodology has been developed to accurately …
