▎ 摘  要

Current investigation deals with the dynamics of a novel class of composites, known as functionally graded graphene reinforced composite (FG-GPLRC) laminated plates subjected to thermal shock. It is assumed that each layer of the composite laminated plate is reinforced with different amount of GPLs which results in a piecewise functionally graded media. Plate is subjected to different types of thermal boundary conditions such as rapid heat flux, rapid temperature elevation or thermally insulated on the top and bottom surfaces. The one dimensional heat conduction equation is established and solved considering the boundary conditions on the top and bottom surfaces and also continuity of temperature and heat flux among the layers. Thermal force and thermal moment resultants are evaluated at each time step after evaluation of temperature profile. The dynamic equations of the plate are established by means of the first order shear deformation theory and the Ritz method where shape functions are estimated via the Chebyshev polynomials. The adopted method is general and may be used for arbitrary combinations of boundary conditions. Thermally induced vibrations of FG-GPLRC plates are studied for various weight fractions of GPLs, different patterns of GPLs, various mechanical and thermal boundary conditions. It is shown that thermally induced vibrations indeed exist.
