The Geometrically Nonlinear Dynamic Response of Metal-Ceramic FGM Plates under the Blast Loading

Functionally Graded Materials (FGMs) are kinds of composite materials which exhibit continuous variation of material properties from one surface to another. With regard to the continuity of mixture of constituent materials, FGMs have more effective mechanical properties compared to laminated composi...
