Antisymmetric and Symmetric Functionally Graded Plate-Type Structures Impacted by Blast Loading
Abstract
The foundation of the theory of functionally graded plates with simply supported edges, under a Friedlander explosive air-blast, are developed within the classical plate theory (CPT). Within the development of the theory, the two constituent phases, ceramic and metal, vary across the wall thickness according to a prescribed power law. The theory includes the geometrical nonlinearities, the dynamic effects, compressive tensile edge loadings,and the damping effects. Also presented are the analytical expressions for the stresses, in which the results of which are not presented here. The static and dynamic solutions are developed leveraging the use of a stress potential with the Extended-Galerkin method and the Runge-Kutta method. The analysis focuses on how to alleviate the effects of large deformations through proper material selection and the proper gradation of the constituent phases or materials.
