The paper deals with the testing and modelling of metals response when subjected to sheet
forming operations. The focus is both on the modelling of hardening behaviour and yield …

This paper reviews the most recent models for description of the anisotropic plastic behavior
and formability of sheet metals. After a brief review of classic isotropic yield functions, recent …

It is challenging to precisely model the complicated plastic deformation of metals, including
anisotropy in strength and plastic deformation, strength differential effect, anisotropic …

We introduce a microstructurally informed machine learning model for predicting the
anisotropic yield surfaces of polycrystalline materials. A full-field, spatially resolved crystal …

The correct description of initial plastic anisotropy of metallic sheets plays a key role in
modelling of sheet forming processes since prediction of material flow, residual stresses and …

Analytical Poly6–18p yield criterion by considering both pure shear and plane strain states
has been developed. The convex relationship of analytical Poly6-type yield criteria between …

We present a virtual laboratory to investigate the anisotropic yield behavior of polycrystalline
materials by using high resolution crystal plasticity simulations. Employing a fast spectral …

A sixth-order polynomial type 3D yield function, which has a high flexibility of describing
anisotropic behavior of steel sheet, is proposed. The yield function is constructed as a sum …

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 …

An anisotropic plane stress yield function based on interpolation by second order Bézier
curves is proposed. The parameters for the model are readily derived by four mechanical …
