This paper analyses geometrically nonlinear transient response of laminated composite plates with delaminations, using FEM. Numerical model is based on Reddy’s Generalized Laminated Plate Theory. Geometric nonlinearity is accounted using von Karman strain field. Delamination openings in three orthogonal directions are implemented using Heaviside step functions. Equations of motion are derived using Hamilton’s principle. Partial differential equations are reduced to a set of ordinary differential equations in time using Newmark’s integration schemes. Nonlinear equations of motion are solved using constant average acceleration method and Picard’s algorithm. Effects of crack size and position on transient response are shown.
