摘要

In this work, a one-dimensional problem for an infinitely long circular cylinder is solved by an eigenvalue approach. The outer surface of this cylinder is traction free and subjected to a thermal shock. The problem is in the context of the theory of generalized thermoelasticity with one relaxation time parameter. The Laplace transform technuiqe is used. The solution in the transformed domain is obtained by a direct eigenvalue approach. The inversion of the Laplace transform solution is evaluated numerically. Numerical results are obtained and represented graphically for two cases and finally compared with the current results available in the literature. eigenvalue approach; generalized thermoelasticity; Laplace transform; vector-matrix differential
