摘要

采用Abaqus软件建立有限元模型,分析了激光功率密度对孔周表面残余主应力分布的影响。进行了不同功率密度下的激光喷丸(LP)试验,通过X射线应力分析仪测量了孔周区域特征点三个方向的残余应力值,并计算了各点对应的主应力。结果表明,LP之后孔周的残余应力呈现各向异性;最小残余主应力可有效表征喷丸强化效果,随着激光功率密度的提高,最小残余主应力值减小。另外,LP后小孔附近出现典型的残余压应力环,最小残余主应力明显小于其他喷丸区域的;当功率密度超过一定阈值时,此环呈现远离孔壁的趋势。

Abstract

A finite element model is developed by Abaqus software to investigate the effect of laser power density on the residual principal stress distribution on the surface around the hole. Laser peening (LP) experiments under different power densities are conducted, and the residual stresses of feature points around holes are measured along three directions by X-ray diffraction stress analyzer, and the corresponding principal stress of each test point is calculated. The results indicate that the residual stress is anisotropic on the surface around the hole after LP. The minimum residual principal stress is an effective indicator to characterize the LP effect, which decreases with the increment of laser power density. In addition, a typical residual compressive stress ring occurs around the hole after LP, where the minimum residual principal stress value is obviously less than that in other peening zones. When the laser power density exceeds a certain threshold value, this ring has a tendency to be away from the hole wall.
