摘要

在本工作中，提出了一个简单的公式来评估凸嵌入多边形裂纹的应力强度因子（SIF）。该公式被构造为Oore Burns方程的校正因子，并基于精确的三维有限元分析。此外，还给出了规则多边形裂纹的精确计算公式。

The Stress Intensity Factor of convex embedded polygonal cracks

In the present work, a simple formula for the evaluation of the stress intensity factor (SIF) of convex embedded polygonal cracks has been proposed. This formula is structured as a correction factor of the Oore-Burns’ equation and is based on accurate three-dimensional FE analysis. Furthermore, a precise formula for a regular polygonal crack has been given.
