Magnesium sheet metal alloys have a hexagonal close packed (hcp) crystal structure that leads to severe evolving anisotropy and tension-compression asymmetry as a result of the activation of different deformation mechanisms (slip and twinning) that a

International audience; Plastic instabilities such as diffuse or localized necking may occur during sheet metal forming processes, thus limiting sheet metal formability, which is detrimental to industry. The formability of sheet metals is usually cha

Asymptotic fields of mode I steady-state crack propagation in non-associative elastoplastic solid

Autor: Davide Bigoni, Enrico Radi

The quasi-static, steady-state propagation of a crack running in an elastoplastic solid with volumetric-non-associative flow law is analyzed. The adopted constitutive model corresponds to the small strain version of that proposed by Rudnicki and Rice
