【Abstract】 Based on FEM the problem in time domain is transformed into a problem in Laplace domain by Laplace transform. A Laplace transform finite element method solving transient temperature field of composite laminates is proposed. The method formulate and solve finite element equations in the Laplace donaim and then by the inverse Laplace transform in numerical form the solutions in the time domain are obtained. Examples show that the method is successful.更多还原
