An Analysis of Collinear Periodic Crack-Tip Stress Field of an Infinite Plate Subjected to Concentrated Force
The Stress field of collinear periodic cracks in an infinite orthotropic composite plate subjected to the concentrated force is studied.The mechanical problem is turned into partial differential boundary value problem.The solution of partial differential equations can be obtained by the complex function methods,which contains unknown coefficients.Using undetermined coefficients method and with the help of boundary conditions,the partial differential boundary value problem is solved.The expressions for stress and displacements near crack tip are derived.Since the distribution of periodic cracks,the stress intensity factor is related to crack shape.Finally,a numerical example shows that the stress changes with the polar angle.
