Optimization of Eleven Cross-Roll Straightening Process for 20CrMnTi Bars Based on Combined Hardening Model

Metals
Straightness is one of the important indices to measure the quality of bars; multi-roll straightening is an essential process in bar production.

Characterisation and modelling of anisotropic hardening behaviour of cubic and hexagonal close packed polycrystalline metals

Philosophical Magazine Letters
In this study, anisotropic non-proportional hardening behaviour of the sheet metals with different crystalline structures is investigated. The investigated materials particularly exhibit the Bauschinger effect and complex transient hardening behaviour ...

Cyclic plastic behavior and springback prediction of QP980 high strength steel in roll forming

Cailiao gongcheng
In the roll forming， the sheet metal will experience multiple bending processes. The nonlinear hardening behavior and cyclic plastic behavior of high strength steel during multiple bending deformation， such as Bauschinger effect and cyclic hardening ...

Study of Work-Hardening Rate Transient of AISI 409 Stainless Steel Under Strain Path Changes [PDF]

Materials Research
Metal forming processes present many changes in the strain path necessary to obtain the dimensions and shape of a metal part. The loading mode, the amount of prestrain, the initial state of a material and its respective substructural arrangements affect ...

A Transition State Theory-Based Continuum Plasticity Model Accounting for the Local Stress Fluctuation

Metals
Based on the transition state theory, a continuum plasticity theory is developed for metallic materials. Moreover, the nature of local stress fluctuation within a material point is considered by incorporating the probability distribution of the stresses.
