Abstract [en]

A simulation approach based on computational welding mechanics (CWM) is presented for an industrial context, aircraft engine manufacturing, where safety is of paramount importance, the technology transfer process developed at Volvo Aero Corporation to ensure qualified welding simulations is described, and a modelling methodology including calibration and validation procedures is outlined. Aspects of the simulation and modelling methodologies are discussed such as accuracy levels and the shortcomings of thermomechanical models and finite element analysis. The use of strain rate jump tests and Satoh tests for CWM validation is analysed and application to the turbine exhaust case of the PW2000 engine is reported
