摘要

The present paper deals with the stability problem of a thin circular thin plate which is stiffened by a thin cylindrical shell on the external boundary or inside the plate. Assuming axisymmetric deformations and an axisymmetric in-plane load we determine the critical value of the load in order to clarify what is the effect of the stiffening shell. Using Kirchhoff s theory of thin shells and plates the paper presents the governing equations both for the circular plate and for the cylindrical shell, the boundary- and continuity conditions and last but not least numerical results as well.
