| Abstract: | Based on the fundamental solution, some basic problems of the boundary element method on orthotropic composite material plate including C mains, G(ij) matrix, H(ij) matrix and stress formulae of internal region are studied. The calculation formulae of the constant boundary element and liner boundary element are built up.The theory and formulac are suitable for various boundary problems. Aocording to the formulae, an analysis for orthotropic plate with central cracks and infinite orthotropic plate with round holes is presented.The calculating result is satisfactory. |
