摘要：

The boundary integral equation (BIE) method for three-dimensional, linear, elastic stress analysis is applied to some stress concentration problems associated with oblique circular holes in flat plates subject to in-plane tensile loading. Satisfactory agreement is obtained with both an analytical solution for a normal hole and previously published experimental results for oblique holes. Computed maximum stress concentration factors are generally higher than those obtained experimentally, and are very sensitive to changes in the angle of obliquity. Results are presented for three relative plate thicknesses, and in one case for two directions of loading. The BIE method is shown to be a very useful tool for solving problems of engineering stress and strain analysis. © 1979, Institution of Mechanical Engineers. All rights reserved.
