Abstract
The adhesion failures between the layers of a composite material are related to the thermal contact conductance, therefore this work aims to estimate this parameter in a laminated composite. To solve the direct problem, the Method of Lines was applied, while the inverse problem was solved by a Bayesian filter called Unscented Kalman Filter. The physical problem used in this study is composed of a plate with two layers, so the heat transfer problem has two spatial dimensions and a time dimension. Then, the values assigned for thermal conductance on interface layer depends on time and space. In this work, in order to analyze the proposed methodology, simulated temperature measurements were used. The results reveal the capability of the proposed approach.
