Recent reports in the literature identified pre-yield stress-strain nonlinearity and hysteresis
(anelasticity) as occurring in metals at virtually all stresses. These observations raise …

Industrial servo presses have been used to successfully demonstrate improved formability
when deforming sheet metals. While the time dependent viscoplastic behavior of material is …

Unloading-reloading behavior is of crucial importance in multi-pass forming of metal
materials, the nonlinear of which creates challenges for the analysis of springback and …

A general meso‑scale (GM) crystal plasticity (CP) model was developed that accounts for
lower-order (strain hardening) and higher-order (internal stress) effects of geometrically …

Abstract The Johnson-Cook (JC) model, including a constitutive model and a failure
criterion, is an empirical model that is widely used in various fields to implement large …

For an accurate numerical simulation of springback behavior and control of shape and
dimensional accuracies of the manufacture component under warm and hot precision plastic …

Sheet metal forming is among the most widely employed processes in manufacturing. Its
economic feasibility relies on many factors, including the mechanical properties of the …

Quenching and partitioning (Q&P) treatment has been proven effective in manufacturing
advanced high strength steels with high content of retained austenite, showing the improved …
