An a priori error analysis of a type III thermoelastic problem with two porosities

open access: yesNumerical Methods for Partial Differential Equations, Volume 39, Issue 2, Page 1067-1084, March 2023., 2023
Abstract In this work, we study, from the numerical point of view, a type III thermoelastic model with double porosity. The thermomechanical problem is written as a linear system composed of hyperbolic partial differential equations for the displacements and the two porosities, and a parabolic partial differential equation for the thermal displacement.
