【Abstract】 Finite element analysis and experimental test were performed on the braze residual stress between two materials that have different expansion coefficients,and the rationality and reliability of the finite element model was estimated.The results of test and finite element analysis have certain consistency,which suggests that the residual stress obtained from the finite element analysis can provide rational and reliable reference for understanding the actual residual stress of the devices.更多还原
