A nonlinear stability analysis of imperfect three-phase polymer composite plates
Tóm tắt
An analytical investigation into the nonlinear response of a thin imperfect laminated three-phase polymer composite plate consisting of a matrix and reinforcing fibers and particles and subjected to mechanical loads is presented. All formulations are based on the classical theory of plates with account of interaction between the matrix and reinforcement, the geometrical nonlinearity, and an initial geometrical imperfection. By using the Galerkin method, explicit relations for the load–deflection relationships are determined. The effects of reinforcing fibers and particles, material and geometrical properties, and imperfections on the buckling and postbuckling load-carrying capacities of a 3-phase composite plate are analyzed and discussed.
