Bauschinger effect and springback behavior of dual phase sheet steels

, 2007
With the increasing use of advanced high strength steels in the automotive industry, springback control has become a more critical issue. It is now realized that a more accurate simulation of springback has to take the Bauschinger effect into account ...

Investigating Bauschinger Effect and Plastic Hardening Characteristics of Sheet Metal under Cyclic Loading

, 2017
To improve sheet metal forming process simulation using finite element method, there is a need to incorporate an appropriate constitutive equation capable of describing the Bauschinger effect and the so-called cyclic transient, derived from a near to ...

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 ...

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 ...

DAMAGE AND STRESS STATE INFLUENCE ON BAUSCHINGER EFFECT IN ALUMINUM ALLOYS

, 2006
In this work, the Bauschinger effect is shown to be intimately tied not only to plasticity but to damage as well. The plasticity-damage effect on the Bauschinger effect is demonstrated by employing different definitions (Bauschinger Stress Parameter ...

Effects of Microstructure and Pre-strain on Bauschinger Effect in API X70 and X80 Linepipe Steels

, 2018
In this study, effects of microstructure and pre-strain on the Bauschinger effect were investigated in two API X70 and two API X80 linepipe steel sheets fabricated by controlling the cooling condition, and their yield strength and Bauschinger parameters ...

Changes in the Bauschinger Effect Level Post the Autofrettage Process

, 2009
The favorable residual stress field generated by the autofrettage process is increasing the barrel’s capacity to withstand pressure during firing — defined as the re-loading phase.
