This paper investigates the transient thermal performance of stratified fluid-filled geomaterials with compressible constituents due to a buried decaying heat source. Starting with the governing partial differential equations, the ordinary differential matrix equation is derived by means of Laplace transform and Hankel transform. Using the extended precise integration method, the ordinary differential...
This paper focuses on the investigation of the response of a vertically loaded rigid circular disc embedded in a transversely isotropic multilayered half-space. The solutions for this dynamic interaction problem are obtained by utilizing the boundary element method, which takes the analytical layer-element solution of the transversely isotropic multilayered half-space subjected to an interior ring...
Most thermal stress analyses are based on the uncoupled theory of thermoelasticity, which considers that the determination of the temperature field is independent from the stress and displacement fields. This paper derives an extended precise integration solution for the coupled thermoelastic problems with the integral transformation techniques. From the axisymmetric fundamental governing equations,...
This paper presents a numerically efficient and stable method to study the thermoelastic problem of layered medium containing a heat source. Based on the governing equations of 3D thermoelasticity, the relationship between generalized displacements and stresses of a single layer is described by an analytical layer-element, which is obtained in the Laplace–Fourier transformed domain by using the eigenvalue...
