1 Vol. 8 ( ) Finite Element of Composite aterials with Partial Debonding along Boundary Kohei HIGUCHI, Tetsuo IWAKUA JFE PhD Damages in composite materials are mostly governed by interfacial debonding. In order to take this into account, we employ an analytical model considering partial debonding along interface, and formulate a finite element. The model utilizes a concept where a moduli of an inclusion is replaced by an equivalent one of debonded inclusions. By several examples, eligibility of the model is shown. As an application, excavation analysis of a tunnel in jointed rock mass is carried out, and the results are compared with other observations. Key Words : composites, partial debonding, ori-tanaka theory, finite element 1.
