A computational strategy for thermo-poroelastic structures with a time-space interface coupling

چکیده
This paper deals with a computational strategy suitable for the simulation of multiphysics problems, based on the Large Time INcrement (LATIN) method. The simulation of such problems must encounter the possible different time and space scales which usually arise with the different physics. Herein, we focus on using different time and space discretizations for each physics by introducing an interface with its own discretization. The feasibility of both a time and space couplings is exemplified on a nonlinear 3-physics strongly coupled problem: the thermal / fluid / structure interaction in a thermo-poroelastic structure. This is the post-print accepted version of the following article: D. Néron, D. Dureisseix, A computational strategy for thermo-poroelastic structures with a time-space interface coupling, International Journal for Numerical Methods in Engineering 75(9):1053-1084, Wiley, 2008, DOI: 10.1002/nme.2283, which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1002/nme.2283/abstract

A computational strategy for poroelastic problems with a time interface between coupled physics
This paper deals with a computational strategy suitable for the simulation of multiphysics problems and based on the Large Time INcrement (LATIN) method. One of the main issues in the design of advanced tools for the simulation of such problems is to take into account the different time and space scales which usually arise with the different physics. Here, we focus on using different time discr...
متن کاملAn Algorithm for Modeling and Interpretation of Seismoelectric Data
Generally speaking, seismoelectric modeling is a prospecting method based on seismic and electromagnetic waves, in which waves generated by a seismic source at the boundary of the two environments generate a relative fluid-solid motion formed as a result of antagonism between the elastic properties of the environment with the saturated fluid. This research has as its objective, a study of the e...
متن کاملPlane Strain Deformation of a Poroelastic Half-Space Lying Over Another Poroelastic Half-Space
The plane strain deformation of an isotropic, homogeneous, poroelastic medium caused by an inclined line-load is studied using the Biot linearized theory for fluid saturated porous materials. The analytical expressions for the displacements and stresses in the medium are obtained by applying suitable boundary conditions. The solutions are obtained analytically for the limiting case of undrained...
متن کاملCoupling Nonlinear Element Free Galerkin and Linear Galerkin Finite Volume Solver for 2D Modeling of Local Plasticity in Structural Material
This paper introduces a computational strategy to collaboratively develop the Galerkin Finite Volume Method (GFVM) as one of the most straightforward and efficient explicit numerical methods to solve structural problems encountering material nonlinearity in a small limited area, while the remainder of the domain represents a linear elastic behavior. In this regard, the Element Free Galerkin met...
متن کاملThermo-mechanical nonlinear vibration analysis of fluid-conveying structures subjected to different boundary conditions using Galerkin-Newton-Harmonic balancing method
The development of mathematical models for describing the dynamic behaviours of fluid conveying pipes, micro-pipes and nanotubes under the influence of some thermo-mechanical parameters results into nonlinear equations that are very difficult to solve analytically. In cases where the exact analytical solutions are presented either in implicit or explicit forms, high skills and rigorous mathemat...
