| Abstract: | A study of double dissimilar orthotropic composite material in non-principal directions of elasticity interfacial crack problem was made.The stress and strain of non-parallel axis principal directions of elasticity transformation formulas was used.When the discriminations of characteristic equations are less than zero,the theoretical formula of the stress field and displacement near crack tip can be obtained by using complex functions methods of composite material fracture,and their influences on the stress field are investigated. |
