Thermodynamique Résumé : We present a new model for the determination of temperature distributions in thin plates consisting of many different layers. The method uses both continuous and discrete approaches. The derived set of equations is based on a continuous representation of heat transfer phenomena at the midplane of each layer, whereas it facilitates a discrete process for introducing ply to ply, through thickness, heat transfer. For the steady state case, the resulting equations are of the Helmholtz type. Methods of solutions for the resulting system are discussed, and comparisons with the first order lamination theory are presented in a benchmark example.

Heat transfer in thin multilayered plates.Part II; Applications to the composite patch repair technique / T. K. Papathanasiou in Journal of heat transfer, Vol. 133 N° 2 (Fevrier 2011)

Filopoulos, Auteur Année de publication : 2011 Article en page(s) : pp. [021303/1-7] Note générale : Physique Langues : Anglais (eng) Mots-clés : Heat  transfer  Extended  surfaces  Composite  patch  repair  Multilayered  plates Index. décimale : 536 Chaleur. Thermodynamique Résumé : This second part of our contribution entitled, “Heat Transfer in Thin Multilayered Plates,” refers to the modeling of an advanced repair technique, known as the composite patch repair (CPR). Thermal analysis of this particular application is highly complicated due to the geometry of the domains and the fact that many different materials participate in the implementation. In this paper, we take advantage of the fact that both the composite patch and the damaged plate to be repaired are of very small thickness. In that way, the whole domain may be treated as a thin multilayer area of extended surface. These properties make the thermal analysis of CPR an ideal field for using the method presented in the previous part of our analysis.
