FEM prediction of welding residual stress and distortion in carbon steel considering phase transformation effects
TL;DR: In this article, the authors investigated the effects of solid-state phase transformation on welding residual stress and distortion in low carbon and medium carbon steels, based on a sequentially coupled thermal, metallurgical, mechanical 3-D finite element model.

Physical processes in fusion welding
Tarasankar Debroy,Stan A David +1 more
TL;DR: In recent years, major advances have taken place in our understanding of welding processes and welded materials because of the complexity of fusion welding processes, solution of many important contemporary problems in fusion welding requires an interdisciplinary approach as mentioned in this paper.

Hot stamping of boron steel sheets with tailored properties: A review
TL;DR: A review of the main research activities recently carried out in the framework of hot stamping of boron steel sheets with tailored properties is given in this article, where the focus is on the process variants developed to locally adjust the mechanical properties of the hot stamped component as well as on the testing and modeling techniques needed to calibrate the numerical models of the tailored tempering processes and to evaluate the post-forming properties of stamped products.

EDM simulation: finite element-based calculation of deformation, microstructure and residual stresses
TL;DR: In this paper, a finite element-based model for the electric discharge machining (EDM) process is presented, which uses process parameters such as power input, pulse duration, etc., to predict the transient temperature distribution, liquid-and solid-state material transformation, and residual stresses that are induced in the workpiece as a result of a single-pulse discharge.

A new finite element model for welding heat sources
TL;DR: In this article, a double ellipsoidal geometry is proposed to model both shallow penetration arc welding processes and the deeper penetration laser and electron beam processes, which can be easily changed to handle non-axisymmetric cases such as strip electrodes or dissimilar metal joining.
Journal ArticleDOI
Transformation kinetics during continuous cooling
TL;DR: In this article, it was shown that transformations which nucleate heterogeneously will quite often obey a rule of additivity and transform nonisothermally according to simple rate laws which can be calculated from isothermal transformation data.
Journal ArticleDOI
A first report on diagrams for grain growth in welds
TL;DR: In this article, a set of poorly-known kinetic constants which appear in such a treatment are determined by fitting the equations to data from real or simulated welds, at certain fixed points.
