Residual Stress Analysis on Welded Joints by Means of Numerical Simulation and Experiments
One of the main problems of gas metal arc welding (GMAW) process is the generation of residual stresses (RS), which has a direct impact on the mechanical performance of welded components. Nevertheless, RS pattern prediction is complex and requires the simulation of the welding process. Consequently, most of the currently used dimensioning approaches do not consider RS, leading to design oversized structures. This fact is especially relevant in big structures since it generates high material,doi:10.5772/intechopen.72134 fatcat:dfis33yf3jhapdm6ugtsotsene
