Finite element analysis of a single bead-on-plate specimen using SYSWELD

An uncoupled thermal and mechanical analysis has been carried out using the software code, SYSWELD in order to model a single bead-on-plate specimen. The heat source is represented by the Goldak double ellipsoid model which is available within the code. The parameters of this model were defined by the welding parameters and the macrographs and thermocouple data provided in the benchmark. The mechanical analysis is based on an isotropic hardening model which is defined by the tensile data provided in the protocol. Annealing is assumed at a temperature of 1400 °C. This paper describes the heat source fitting, the subsequent thermal and mechanical analyses and presents selected results.
