MACRO MICRO MODEL FOR ANALYZING THE FRACTURE OF FIBER REINFORCED COMPOSITE MATERIAL

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.
