Investigation of deformation and failure features in hot stamping of AA6082: Experimentation and modelling
TL;DR: In this paper, a set of coupled viscoplastic constitutive equations for deformation and damage in hot stamping and cold die quenching of AA6082 panel parts are introduced.
Journal ArticleDOI
The development of continuum damage mechanics-based theories for predicting forming limit diagrams for hot stamping applications:
TL;DR: In this paper, a plane-stress continuum damage mechanics (CDM) model for the prediction of the different shapes of forming limit diagrams (FLCs) for aluminium alloys under hot stamping conditions is presented.
Journal ArticleDOI
Application of a continuum damage mechanics (CDM)-based model for predicting formability of warm formed aluminium alloy
TL;DR: In this article, the constitutive model is implemented in Ls-Dyna user subroutine to predict the formability of sheet metal in warm/hot forming processes, and the finite element (FE) result of strain distribution was compared with the experimental result from Argus system in terms of different strain paths.
Journal ArticleDOI
Experimental investigation of boron steel at hot stamping conditions
Nan Li,Chaoyang Sun,N. Guo,Mohamed Mohamed,Jianguo Lin,Jianguo Lin,Takeki Matsumoto,Chao Liu +7 more
TL;DR: In this paper, the effect of deformation temperature and strain rate on the fracture and strain hardening of boron steel was investigated through the analysis of large amount of experimental data tested using a Gleeble (3800) materials simulator.
Proceedings ArticleDOI
Experimental and Numerical Studies on the Formability of Materials in Hot Stamping and Cold Die Quenching Processes
TL;DR: In this paper, a simulation model and numerical procedures are established for the modeling of hot stamping processes for a spherical part with a central hole, and different failure modes (failure takes place either near the central hole or in the mid span of the part) are obtained.
