Abstract

The economic challenge for PSA regarding the maintenance of their mould foundry park isto predict and improve its lifespan in preventing any risk of initiation and propagationof cracks in thermal fatigue. A method for assessing the number of cycles of castingtooling thermal fatigue used by PSA was developed using the criterion of Fatemi-Socie [A.Fatemi, D. Socie, Fatigue Fract. Engng.Mater. Struct. 11 (1988) 149-165, D.F.Socie, multiaxial fatigue damage models, ASME 109 (1987)293-298], associated with a shear failure mode, which predicts the thermal fatigue damageby assessing stress and strain tensors on different facets around any material point.
