An Analysis of Fracture Problems of Orthotropic Composite Plate under Bending and Twisting

摘要

An analysis of fracture problems near crack tip for linear elastic Orthotropic composite plate under bending and twisting is carried out. By solving the boundary value problem of partial differential equations and applying the method of undetermined coefficients, the two group expressions for bending moment, twisting moment and displacement near crack tip are derived. The formulae have certain practical and referential value in related fracture analysis.
