A method for quantifying distortions arising in engine blocks of aluminium with liners of grey iron has been developed. The engine block has been modelled using the finite element method and machining has been simulated using the element-removal technique. The mechanical behaviour of aluminium has been characterised by tensile tests at different temperatures and strain rates. The results were used for calibration of material models capturing the viscoplastic behaviour at higher temperatures.

Nyckelord: Process simulation, residual stresses, distortion, out of roundness, FE-simulation
