It is 100 years since the well-known Mohr-Coulomb strength theory was established in 1900.
A considerable amount of theoretical and experimental research on strength theory of …

The prediction of earing during cup-drawing of the anisotropic aluminum alloy Al-6022-T4 is
studied through a combination of experiments and analysis. At first, the anisotropy of the …

Tailor-welded blanks made of dissimilar, uniform or non-uniform thickness materials have
potential applications in automobile industries. Compared to the base metal, the formability …

Robustness of numerical models paves the way for efficient compensation of perturbations
resulting in deviations from the nominal conditions. This is critical if the numerical …

A Tailor-Welded Blank (TWB) consists of steels of different thicknesses, strength types
welded together to produce a single blank prior to the forming process. TWBs offer several …

The recent trend to reduce the thickness of metallic sheets used in forming processes
strongly increases the likelihood of the occurrence of wrinkling. Thus, in order to obtain …

This paper aims at investigating the effects of the martensitic phase transformation on the
formability of unstable austenitic steel sheets. To this end, the constitutive model developed …

The onset of wrinkling in sheet metal forming is investigated using an analytical approach
and finite element (FE) simulations. In both cases the yield criterion proposed by Ferron et …

Deep drawing is an extensively used press working process since it eliminates expensive
machining and welding operations and enables the production of components at a very high …

An analysis of the onset of wrinkling is first developed for a doubly curved, elastic–plastic
shell element submitted to a biaxial plane stress loading. Plastic yielding is described using …
