M. T. Cao-Rial, G. Castiñeira, Á. Rodríguez-Arós, S. Roscani

摘要:

本文考虑一类三维线性椭圆膜壳热弹性问题,研究了当膜壳厚度趋于零时解的渐近性态,充分刻画了极限为二维问题的唯一解的强收敛性结果,其中参考域为三维壳族的公共中面。问题是动态的,本构热弹性定律由Duhamel-Neumann关系给出。

英文摘要:

In this paper we consider a family of three-dimensional problems in thermoelasticity for linear elliptic membrane shells and study the asymptotic behaviour of the solution when the thickness tends to zero.We fully characterize with strong convergence results the limit as the unique solution of a two-dimensional problem, where the reference domain is the common middle surface of the family of three-dimensional shells. The problems are dynamic and the constitutive thermoelastic law is given by the Duhamel-Neumann relation.
