%X This article presents the coupled thermoelasticity of a truncated functionallygraded conical shell under thermal shock load. The classicalcoupled thermoelasticity theory is employed to set the partial differentialequations of motion of the conical shell. The shell governingequations are based on the first-order shear deformation shell theorythat accounts for the transverse shear strains and rotations. The solutionis obtained by transforming the governing equations into theLaplace domain and using the Galerkin finite element method in theLaplace domain to calculate the displacement components. The physicaldisplacement components in real time domain are obtained bythe numerical inversion of the Laplace transform. Temperature distributionis assumed to be linear across the shell thickness. Radialdisplacement, axial stress, axial force, and temperature versus timeare calculated and the effect of relaxation time and power law indexare examined. Comparison indicates that an increase in the radial vibrationamplitude and a decrease of vibration frequency occur whenchanging the material from ceramic to metal. The results are validatedwith the known data in the literature.
