Thermomechanical phase change peridynamic model for welding analysis

In numerical welding modelling, it is critically important to adopt a heat source model that fits the actual process since has significant influence on calculation accuracy of transient temperature field, especially near source. An inappropriate can produce an overestimated or underestimated leading displacement field errors in mechanical analysis. this study, new non-linear peridynamic employing variety models developed predict distribution and variation. More importantly, as essential physical phenomenon conduction, phase transformation considered model. The importance how latent change affect also emphasized. simulation results are compared with finite element method results. Close agreements observed which demonstrates capability proposed for thermomechanical analysis modelling.
