DYNAMIC RESPONSE OF THICK PLATES AND SHELLS

A method for solving the nonlinear dynamic problem of moderately thick plates and shells is presented using an incremental finite element method. In the solution the nonlinear shear factor is derived and plastic-fracture stress-strain relationships of progressively fracturing solids are used. Furthermore, an incremental force-displacement relationship is developed using the principle of virtual work. The minimum number of degrees of freedom for an element is employed in order to reduce the computer solution time. Numerical studies are presented to demonstrate the accuracy and efficiency of the method of solution.(a)
