A user-friendly system for simplified evaluation of fracture mechanics parameters: system construction and implementation of stress intensity factors formulas

摘要

In the present study, we have developed a system for evaluating numerous formulas of three-dimensional (3D) stress intensity factors (SIFs) found in literature. In general, this kind of system has to be flexible in extending its functions, andeasy for ordinary engineers to use. In addition, it is important to keep system compact by sharing common functions among various cracks and structure geometries. To meet those requests, the present system has been fully designed based on anobject-oriented programming approach, and built in a personal computer using one of object-oriented languages Visual C++. Its first version contains about 50 different formulas of 3D-SIFs.
