Abstract: In this paper the analysis of orthotropic skew plate under sinusoidal line load is investigated. The analysis is done with polynomial radial basis function base mess free method using first order shear deformation theory (FSDT). A MATLAB code is developed to obtain the solutions. The governing differential equations of plate are obtained using Hamiltonís principle. Effect of orthotropic ration, skew angle and span to thickness ratio is presented.
