摘要

随着体中各种微缺陷的生长，可以产生任意形态的复杂裂纹系统。本文提出了一种复杂分支裂纹的数值模拟技术，使这类系统的分析成为可能。利用本文提出的方法，可以找到应力场、位移场和应力强度因子，并对其进行分析，得出考虑的形态对裂纹稳定性影响的结论。本文还与其他作者在双连杆裂纹问题上的结果进行了比较。

Numerical Modeling of Branched Cracks

With the growth of various microdefects in bodies, complex systems of cracks of arbitrary configuration can be generated. This paper presents a technique for numerical simulation of complex branched cracks, which makes it possible to analyze such systems. Using the method proposed by the authors, it is possible to find the stress and displacement fields as well as the stress intensity factors, the analysis of which leads to the conclusion about the influence of the considered configuration on the crack stability. The paper also contains the comparison with the results of other authors in the problem of a two-link crack.
