摘要

:通过钻孔法和面外ESPI进行残余应力评估,得到了考虑塑性的应力状态估计。在钻孔前,试样中存在塑性区。样品是一个钢复合圆盘,通过在塞子上安装环来组装。利用弹塑性公式中Gadolin的解,得到了考虑覆盖环塑性区形成的复合弹理想塑料盘的初始应力分布。通过与弹性模型计算结果的比较,提出了一种简单的非轴对称应力调整解析算法。考虑了在塑性变形区钻测孔的情况。

DETERMINATION OF THE NON-AXISYMMETRIC STRESS STATE IN THE PLASTICITY ZONE BY THE HOLE-DRILLING METHOD WITH OUT-OF-PLANE ESPI
: The stress state estimates accounting for plasticity are obtained at residual stress evaluation performed by hole-drilling method and out-of-plane ESPI. The plasticity zone in the sample is present prior to the probe hole drilling. The sample is a steel composite disc, assembled by fitting rings on the plug. The initial stress distribution in the composite elastic-ideal plastic disk accounting for the formation of a plastic zone in the covering ring is obtained by the solution of Gadolin in elastoplastic formulation. A simple analytical algorithm to adjust the non-axisymmetric stresses in comparison with the calculation according to the elastic model is developed. The case of probe hole drilling in the area of plastic deformations is considered.
