| Abstract: | By use of the displacement discontinuity fundamental solutions of Reissner's plate, the Displacement Discontinuity Boundary Integral Equation(DDBIE)is derived based on the Betti's reciprocal theorem. Making use of the DDBE and that of plane problems and the Line-Spring model,a method of analysis of the stress intensity factors of surface cracks in Reissner's plates is given. |
