Stress Relief Heat Treatment: Finite Element Simulation

FEA & CFD Based Simulation Design Analysis Virtual prototyping MultiObjective Optimization

Stress relieving reduces residual stresses in the assembly after welding.The Stress Relief Heat Treatment performed including definition of time-temperature curves for heating, holding and cooling phases with individual convective heat transfer to environment definition. FEA Stress relief is modeled taking into account two mechanisms: Stress relaxation due to decreased yield stress of material during heating - Time-dependent creep properties of the material
