Effects of Different Young' s Modulus on Stress Around Cracks in Composite Material Plate

Different Young's Modulus has considerable effects on the stress field.Taking aim at the stress state of composite material plate with crack,the boundary condition problem of crack is solved with the heterogeneous anisotropic elastic theory and complex variable function.The boundary integralequation based on exact boundary conditions is established.The accurate analytic solution of stress field around the crack in the composite materials plate is obtained.Moreover,based on the calculation model,effects of different Young's Modulus on the stress field around the crack in the composite materials plate are investigated.
