Abstract
Functionally graded materials (FGMs) are those whose composition and hence the properties vary gradually as a function of position. As the materials that the body surface and difference of temperature with the inside can bear a severe condition of 1,000 degrees Celsius, the use is expected to strong in heat and mechanics, in the field of aerospace that a concept of FGMs. However, The space mission using space shuttle heavily relies on the perfonnance of FGMs, since space shuttle is protected by FGM panels. Its vely important to understand fracture behavior of FGM Up to now; the evaluation technique has not been developed, due to many complex behaviors of FGMs. In this paper, simulation technique of fracture path prediction in functionally graded materials was successfully developed.
