Asymptotic decomposition in the problem of joined elastic plates

Abstract

In this paper, a method of local perturbations, previously successfully applied to decompose the problem of elasticity in the system of connected thin rods and beams [Kolpakov and Andrianov, 2013], is used to study the asymptotic behaviour of the elasticity problem in connected thin plates. A complete decomposition of the problem, i.e. the separation of the original problem in to the two-dimensional problem of the theory of plates and local problems is proposed. The local problems describe the three-dimensional stress-strain state in the connected plates and can be solved by numerical methods.
