Euromech-Colloquium Nr. a hundred sixty five The shell-theory improvement has replaced its emphasis over the last 20 years. Nonlinear difficulties became its major rationale. however the research was once until eventually lately predominantly dedicated to shells designed for energy and stiffness. Nonlinearity is the following appropriate to buckling, to intensively fluctuate capable pressure states. those are (with exception of a few restrict situations) lined by way of the quasi-shallow shell conception. The emphasis of the nonlinear research starts off to shift additional - to shells that are designed for and truly in a position to huge elastic displacements. those shells, utilized in for over a century, were lately termedj1exible shells. the ecu Mechanics Colloquium a hundred sixty five. used to be focused on the idea of elastic shells in reference to its functions to those shells. The Colloquium was once meant to debate: 1. The formulations of the nonlinear shell conception, varied within the generality of kine­ matic speculation, and within the selection of based variables. 2. The specialization of the shell conception for the category of shells and the respective elastic tension states assuring flexibility. three. probabilities to accommodate the issues of the buckling research of versatile shells, because of the precritial perturbations in their form and rigidity nation. four. equipment of resolution acceptable for the nonlinear flexible-shell difficulties. five. functions of the speculation. there have been seventy one contributors the periods have been presided over (in that order) by means of E. Reissner, J. G. Simmonds, W. T. Koiter, R. C. Tennyson, F. A. Emmerling, E. Rarnm, E. L. Axelrad.
