Abstract

Imperfect transmission conditions modelling a thin reactive 2D intermediate layer between two bonded materials in a dissimilar strip have been derived and analytically analysed in another paper of this issue. In this paper, the validity of these transmission conditions for heat conduction problems has been investigated due to the finite element method (FEM) for two formulations of a reactive layer: namely, based on a constant and a temperature-dependent source or sink formulation. It is shown that the accuracy of the transmission conditions is excellent for the investigated examples.
