✦ Synopsis

Elastic contact between a thick shell of revolution and a rigid plate in the case when the plate is brought into contact with the shell by giving a finite displacement to the plate is analysed by the finite-element method. Field-consistent higher-order strain-displacement relations with vanishing shear stresses on the surfaces are used. A finite element based on these relations is developed and used for the analysis. The contact conditions are imposed by use of the Lagrangian multipliers method, and the resulting minimization problem is solved iteratively. This procedure will lead to reduced memory requirements and computation time.

This article advocates a general procedure for the numerical investigation of pseudo-rigid bodies. The equations of motion for pseudo-rigid bodies are shown to be mathematically equivalent to those corresponding to certain constant-strain ΓΏnite element approximations for general deformable continua.

A procedure for the finite element computation of the limit load of rigid-perfectly plastic solids is presented. The approach is based on the kinematic theorem of limit analysis, which is formulated so as to reduce the problem to the search of the essentially free minimum of a convex, but not everyw
