Simulation of thermomechanical effects from welding

As part of the ShipWeldFlow project, SDU Mechanical Engineering are working to develop a computational model to accurately simulate the thermomechanical effects from welding on large plates. The temperature fields are calculated using a time-dependent heat source simulating the movement of the welding torch. The temperature fields are then coupled to a mechanical response through a thermomechanical and plastic deformation model. The goal is to predict the macroscopic displacements and deformations of large plates, which will be part of large-scale structures such as ship hulls. Once the model has been validated using experimental data, the long-term goal is to use the simulations to optimise the welding sequence to minimise deflections.
