The use of the finite-element method to calculate unsteady temperatures in the cross section of a thin-wall structure
Abstract
The finite-element method in conjunction with the substructure method is used to analyze unsteady temperature fields in a system of thin-wall rods. A family of two-layer schemes is constructed, and their stability is analyzed. Results obtained with the finite-element method are compared with those obtained with the heat-balance method for the nonlinear problem of calculating temperature fields in a multilayer plate subjected to unsteady aerodynamic heating.
