TOPIC TAGS: plate atress distributionj, stress thickness relationship., biharmonic stress distributionj rotational stress distribution, potential stress distributionj~ ~'small. thickness plate ABSTR&CTs The autriors investigate an elasticitk'theory problem for a plate under stresses given on the boundary, They study the behavior of the stressed state when the thickness of the plate is decreased, The methods for constructing ,asMtotio proceeaes for this.problem. were proposed by A. L. Oolldenveyzer in a report at the first All-Union Conference on Theoretical and Applied Mechanics in 196D, and also by several others, The method givep' by the authors in the present work reduces the construction of the awimptotic to~ sequential solution of a series of biharmonic problems., equivalent to a problem in applied theory of flw=e of a plate and inVersion of an infinite matrix# This, matrix does not depend on the Card 1/2 IOWVICH~, 1. 1.
