| Abstract: | Because the conventional approach to fracture analysis is not capable of coping with the degree of complexity required for composite materials, a proper fracture mechanics analysis method for composite material is necessitated. This paper proposes a macro micro model which divides a composite material containing a flaw into local and global regions and deals with the problem in each region by different methods. By means of the finite element analysis, more useful results are obtained. |
