Abstract: Based upon the use of two dimensional theory of anisotropic elasticity the stress and displacement series are developed for the cracked plate subjected to pin loads.The series satisfy all basic equations,the condition of prescribed resultants and single valued condition of dis- placements at pin holes. A generalized variational principle about multi-regions is applied to consider the boundary conditions and interface conditions between subregions.Only line integra- tions exist in variational equations.Numerical studies reveal that convergent results are given by arelatively simple program which reduces data manipulation and CPU time.
Key words: unsymmetric double edge cracks, anisotropic plate, stress intensity factors, analyt-variational method
