A New Method for Analyzing Surface Cracks

Department of Chemical Mechanical Engineering, Nanjing Institute of Chemical Technology, Nanjing

摘要

摘要: 本文作者综合了线弹簧模型及边界元法的优点,开发了一种新的线弹簧边界元法.该方法把表面裂纹这一三维问题简化为拟一维问题,可用于分析受到多种载荷作用的含表面裂纹的板.本文对该方法进行了理论分析和数值验证,报告了计算结果.结果表明,该方法经济有效.利用该方法仅使用个人计算机就可以分析表面裂纹问题.

Abstract: The authors have developed a new line-spring boundary element method in the present paper,which combines the advantage of the line-spring model with that of the boundary element method.This method reduces the three-dimension problem of the surface cracks into a quasi-one-dimension problem and can be used to analyze the surface cracked plate under various loading conditions.In this paper theoretical analyses and numerical verifications are carried out.The calculated results are reported,which indicate that the present method is efficient and can be used to analyze the surface crack problem on a personal computer.
