This paper presents synthetically the most recent models for description of the anisotropic
plastic behavior. The first section gives an overview of the classical models. Further, the …

Sum-of-square based error formulations may be difficult to implement on an inverse analysis
consisting of multiple tension-compression hysteresis loops. Five alternative measures of …

Forming modern advanced high strength steels poses challenges that were not of real
importance in the previous decades. These challenges are the result of the steels' complex …

The anisotropic plastic flow and ductile fracture of AA6013 aluminum sheet is investigated
under quasistatic conditions. The plasticity of the material is probed through uniaxial tension …

Under a standard derivation, the stiffness modulus for the non-associated flow rule is
asymmetric since its plastic potential (for the plastic strain increment under the normality …

The ductile fracture of an AA6111 aluminum sheet after a thermal cycle typical of auto-body
paint-baking is investigated with the hybrid experimental-numerical method. The plastic flow …

Commercial canmaking processes include drawing, redrawing and several ironing
operations. It is experimentally observed that during the drawing and redrawing processes …

This paper presents a new hierarchical multi-scale framework that allows taking into account
evolution of the plastic anisotropy during sheet forming processes. The evolution of …

A combined experimental and computational method was developed to characterize the
yield stress surface and the conjugate plastic strain-rate potential of the AA7075-O extruded …

An entirely new analytical expression describing plastic anisotropy is presented. It is
designed to be used in combination with multilevel models. It makes use of the theory of …
