Journal ArticleDOI
Austenite decomposition during press hardening of a boron steel : Computer simulation and test
Paul Åkerström,Mats Oldenburg +1 more
TL;DR: In this paper, a model to predict the austenite decomposition into ferrite, pearlite, bainite and martensite during arbitrary cooling paths for thin sheet boron steel is used.
Journal ArticleDOI
The position code algorithm for contact searching
TL;DR: A new global search method for general contact systems is developed and implemented in the DYNA3D program, along with a recent contact interface algorithm, and the concept of «position codes» for efficient global contact searching is presented.
Journal ArticleDOI
Numerical implementation of a constitutive model for simulation of hot stamping
TL;DR: In this article, an accurate and robust constitutive model of the hot stamping process is proposed to increase the accuracy of numerical simulations of numerical simulation of hot stampings in order to increase simulation accuracy.
Journal ArticleDOI
Testing and evaluation of material data for analysis of forming and hardening of boron steel components
TL;DR: In this paper, a finite element simulation of a thin-walled tubular beam subjected to high-temperature bending was presented, and the predicted press force showed acceptable agreement with experimental results in the initial part of the process.
Journal ArticleDOI
A finite element model for thermomechanical analysis of sheet metal forming
Greger Bergman,Mats Oldenburg +1 more
TL;DR: In this paper, a thermal model based on explicit time integration is developed and implemented into the explicit finite element code DYNA3D to model simultaneous forming and quenching of thin-walled structures.
