摘要
Abstract
Based on the basic principle of testing residual stress using blind hole method,experimental calibration and plastic correction research were conducted on the strain release coefficients A and B of 5083 aluminum alloy material.The results indicated that when the stress was below 0.6 times the yield strength,the strain release coefficients A and B remained relatively stable.When the stress exceeded 0.6 times the yield strength,A and B showed a significant downward trend.After the implementation of the correction,the absolute value of the relative error within the entire stress range could be controlled within 3.62%.Compared with the calculation results before correction,the testing accuracy had been significantly improved.关键词
