Non-linear dynamics of laminated plates with a higher-order theory and C0 finite elements

摘要: Abstract Impact responses of composite laminates are investigated with C 0 finite elements. A nine-node isoparametric quadrilateral element based on a higher-order theory and the von Karman large deflection assumptions is developed. An experimentally established contact law which accounts for permanent indentation incorporated into program to evaluate impact force. In time integration, explicit central difference technique used in conjunction special mass matrix diagonalization scheme. Numerical results, including force histories, deflections strains plate, presented.
