Measuring the internal stress of Al alloy forgings accurately is critical for controlling the deformation during the subsequent machine *** this work,the crack compliance method was used to calculate the internal residual stress of Al-Cu high strength alloys,and the effect of various model parameters of crack compliance method on the calculated precision was studied by combining the numerical simulation and experimental *** results show that the precision first increased and then decreased with increasing the crack *** decreased precision when using a high crack range was due to the strain fluctuation during the machining process,and the optimized crack range was 71%of the thickness of *** orders of Legendre polynomial can result in residual stress curve more smooth,while high orders led to the occurrence of *** Tikhonov regularization method effectively suppressed the distortion of residual stress caused by the fluctuation of strain data,which significantly improved the *** addition,The crack compliance method with optimized parameters was used to measure the residual stress of Al-Cu alloy with different quenching *** calculated results demonstrated that the distribution of residual stress was obtained accurately.
