크랙이 있는 이방성 접착구조물의 혼합 모우드 해석

Abstract

An adhesively boded anisotropic structure containing a part-through crack subjected to in-plane mixed mode deformations is investgaed. The problem is reduced to a pair of Fredholm integral equations of the second kind by mathmatical analysis. By solving these equations numerically stress intensity factors k1 and k2 are presented. Two cases are considered with respect to fiber orientations. Case one is to fix the fiber orientations of sound plate bonded to cracked plate with various fiber orientations. The other is to vary fiber orientations for both plates.

As boundary conditions, tension and shear loading respectively, are applied to bonded anisotropic plates to obseve mixed deformations.
