Abstract

The present study develops computationally efficient meshless model for the first-ply failure analysis and predicts the weakest ply, based on various failure criteria via one-dimensional, higher-order beam theory. The effective property of lamina is obtained with the help of micromechanics based Eshelby’s-Mori-Tanaka model. The governing equation is obtained with the help of point interpolation method based on polynomial basis function. The effects of different essential and natural boundary conditions, aspect ratio, lamination angle and volume fraction on the first-ply failure load of composite beam is studied.
