Journal ArticleDOI
Finite element modeling using homogeneous anisotropic hardening and application to spring-back prediction
TL;DR: A finite element implementation of the recently proposed constitutive model (Homogeneous yield function-based anisotropic hardening model or HAH) that describes the plastic behavior of materials subjected to multiple strain path changes was developed.
Journal ArticleDOI
An application of homogeneous anisotropic hardening to springback prediction in pre-strained U-draw/bending
TL;DR: In this paper, a constitutive model based on anisotropic hardening was used in the finite element (FE) simulations of springback and its performance was compared with that of conventional hardening laws.
Journal ArticleDOI
Variation and consistency of Young’s modulus in steel
TL;DR: In this article, the authors used high-precision modulus measurements using mechanical testing, resonant frequency damping analysis, and ultrasonic pulse-echo techniques to evaluate the consistency of the behavior of different grades of steel.
Journal ArticleDOI
Extension of quasi-plastic-elastic approach to incorporate complex plastic flow behavior - application to springback of advanced high-strength steels
TL;DR: In this article, a quasi-plastic-elastic strain (QPE) model is proposed to capture the complex plastic flow behavior of sheet metals such as the Bauschinger effect, transient behavior, workhardening stagnation and permanent softening.
Journal ArticleDOI
Experiment and modeling to investigate the effect of stress state, strain and temperature on martensitic phase transformation in TRIP-assisted steel
TL;DR: In this article, the effects of the stress state and temperature on the martensitic phase transformation behavior in a TRIP-assisted steel (TRIP780) were investigated using multi-axial experimental techniques.
