Abstract

Modern three-dimensional construction elements, which are modeled by finite length cylinders and layers, weakened by through-the-thickness holes of rather different cross-sections, usually work under the influence of great physical and mechanical fields. It leads to a necessity of solving a generalized coupled thermoelasticity problem in the case of finite heat spreading velocity. Using F-solutions method the pointed problem was reduced to well-known systems of one-dimensional singular integral equations of the second order, which was reduced to the system of linear algebraic equations by mechanical quadrature method. Effective numeric schemes and software has been developed and used to solve the problems of thermoelastic coupling influence on frequency-amplitude characteristics of finite cylinders and dynamic stresses concentration in a layer, weakened by through-the–thickness holes. Poisson’s ratio influence on thermoelastic stresses distribution in three-dimensional construction elements was showed
