Donato, Patrizia Some corrector results for composites with imperfect interface. (English) Zbl 1129.35008 Rend. Mat. Appl., VII. Ser. 26, No. 2, 189-209 (2006). Summary: We give some corrector results for a problem modelling the stationary heat diffusion in a conductor with two components, a connected one \(\Omega_1^\varepsilon\) and a disconnected one \(\Omega_2^\varepsilon\), consisting of \(\varepsilon\)-periodic connected components of size \(\varepsilon\). The flow of heat is proportional, by mean of a function of order \(\varepsilon^\gamma\), \(\gamma>-1\), to the jump of the temperature field, due to a contact resistance on the interface. We prove a corrector result for the temperature in the component \(\Omega_1^\varepsilon\) . Moreover, for \(-1< \gamma\leq 1\) we prove the strong convergence to zero of the gradient of the temperature in the component \(\Omega_2^\varepsilon\). Due to different a priori estimates, the case \(\gamma>1\) needs to be treated separately.
