Abstract

This work investigates the effect of a thermal shock loading on the multilayer functionally graded graphene platelets reinforced composite (FG-GPLRC) truncated conical shells. Variation of the temperature distribution along the cone thickness is accurately modeled by dividing the cone into a set of mathematical layers. In order to discretize the governing equations in the spatial domain, a layerwise-differential quadrature method (LW-DQM) as a computationally efficient numerical tool in conjunction with the mapping technique is implemented. This transforms the partial differential equations into a system of ordinary differential equations (ODEs) in the temporal domain. Then a multi-step time integration scheme based on a non-uniform rational B-spline (NURBS) interpolation is applied for the solution of nonlinear ODEs. After a preliminary validation of the approach, the effects of different parameters on the transient temperature of the truncated cone are also studied.
