Thermoelastic Interaction in a Three-Dimensional Layered Sandwich Structure
The present article investigates the thermoelastic interaction in a three-dimensional homogeneous and isotropic sandwich structure using the dual-phase-lag (DPL) model of generalized thermoelasticity. The incorporated resulting non-dimensional coupled equations are applied to a specific problem in which a sandwich layer of unidentical homogeneous and isotropic substances is subjected to time-de...
متن کاملConcepts and Application of Three Dimensional Infinite Elements to Soil Structure-Interaction Problems
This study is concerned with the formulation of three dimensional mapped infinite elements with 1/r and 1/ decay types. These infinite elements are coupled with conventional finite elements and their application to some problems of soil structure interaction are discussed. The effeciency of the coupled finite-infinite elements formulation with respect to computational effort, data preparation a...
متن کاملAlgorithms for the coupling of one-dimensional arterial networks with three-dimensional fluid-structure interaction problems
This work is focused on the development of a geometrical multiscale framework for modeling the human cardiovascular system. This approach is designed to deal with different geometrical and mathematical models at the same time, without any preliminary hypotheses on the layout of the general multiscale problem. This flexibility allows to set up a complete arterial tree model of the circulatory sy...
متن کاملCollisions in 3d Fluid Structure Interactions Problems
This paper deals with the system composed by a rigid ball moving into a viscous incompressible fluid, over a fixed horizontal plane. The equations of motion for the fluid are the Navier–Stokes equations and the equations for the motion of the rigid ball are obtained by applying Newton’s laws. We show that for any weak solution of the corresponding system satisfying the energy inequality, the ri...
متن کاملCoupled Shell-fluid Interaction Problems with Degenerate Shell and Three-dimensional Fluid Elements
Discrete methods for practical coupled three-dimensional fluid-structure interaction problems are developed. A Co explicitly integrated two-dimensional degenerate shell element and a three-dimensional fluid element are coupled to study shell dynamics, fluid transient and coupled shell-fluid interaction problems. The method of partitioning is used to integrate the fluid and shell meshes in a sta...
