摘要: This study deals with the mechanical behaviour and material modelling of an AA5754-O alloy at elevated temperature. Experimental shear tests were performed from room temperature up to 200°C, has been identified both tensile tests, as a function To analyse influence during forming over springback, split-ring test is used. results are obtained compared numerical simulations finite element in-house code DD3IMP. The process ring splitting DD3TRIM. main observed data force-displacement curves punch forming, cup thickness end gap after splitting. It shown that all these parameters strongly dependent on A correlation between experimental simulation for evolution force opening springback distribution tangential stress in wall factor influencing mechanism warm condition.
