## 課程概述 Course Description

「破壞力學」以研究材料之破壞為手段﹐以防止材料破裂為終極目標﹐ 而「破壞力學」則是應用理論來研究材料之破壞原因「破壞力學」用 於設計之上﹐可將一些可能引起破裂之因素與條件﹐在設計之初就加 以考慮以杜絕結構破裂之發生。
"fracture mechanics" is to research fracture material as a means to prevent the material from cracking as the ultimate goal, and " fracture mechanics " theory is applied to study the reasons for the material fractures. Some possible causes/conditions of rupture are considered early in the design in order to prevent the occurrence of cracking of the structure.
