The analysis of viscoelastic stress of thick laminated composite cylinders at an elevated temperature
Abstract
The linear quasistatic thermal viscoelastic behavior of a threedimensional thick laminated composite cylinder with an elevated temperature change is studied in the following research. A closed form formulation of each individual layer with the assumption of the state of generalized plane strain is employed for the analytical solution of the corresponding thermoelastic problem. Then, the correspondence principle is applied on the thermorheologically simple material for the Laplace transformed solution. This Laplace transformed solution is completed by satisfying the boundary conditions and continuity conditions between adjacent layers. Furthermore, a technique of replacing two undetermined coefficients in the solution by the normal stresses at inner and outer surfaces of each layer and applying the normal continuity conditions is developed to solve the resulting smaller system of equations. Finally, the direct Laplace inverse transformation method is incorporated to yield the time dependent viscoelastic result.
