Thermal-stress Analysis of Beam Loaded by 3 Point Bending

Comparison of FE analysis and experimentally obtained data for the identification of residual stresses in welded high-strength steel

“…Residual stresses have arisen in the vicinity of the welding area after laser welding. The laser welding causes thermal changes in thermo-mechanically modified material and its concentrated energy source with low heat dissipation reduces the original stresses in the material [5,6]. The test specimen of DOMEX 700MC high-strength steel welded in both ways is shown in Fig.…”

“…Different residual stresses in comparison to the base material have arisen in the vicinity of the weld joint for both types of welding. The authors anticipated an increased influence of arc welding on the stress change before the measurement, therefore a larger sample area than in laser welding was evaluated [1,6].…”

Numerical simulation of blanking process

“…The punch, blank holders, v-ring indenter and die were modelled as rigid bodies [14]. Rigid target contact was used for contact of punch blank holders and die with sheet metal [15][16][17].…”

Application of analytical methods for determination of hardness distribution in welded joint made of S1100QL steel

“…The exemplary of prediction of hardness distribution in the cross section of flat butt welded by electric arc made of S100QL steel was performed in this study. Field temperature of welded joint was determined on the basis of finite element methods [11,12,13] in ABAQUS FEA software. The analysis of thermal phenomena is made on the basis of the solution of energy conservation equation together with Fourier law [14].…”
