Unilateral Contact Between a Geometrically Non-Linear Plate and Elastic Foundation. A Model of Delamination Phenomena in
The unilateral problem of a circular geometrically non-linear plate which rests on an elastic foundation is investigated. Between the foundation and the plate there exists a connection with a given bounded ultimate (failure) tensile stress. Naturally, a r

PREFACE
This Volume collects the texts of the contributions to the third Meeting on Unilateral Problems in Structural Analysis, held at Villa Emma in the Prescudin Valley, near Udine, on June 17 to 20, 1985. The first two meetings took place at Villa Emma, on May 1982, and at Ravello, on the Amalfi Coast in Southern Italy, on September 1983. The first one was very informal in character, but resulted in an important occasion of contact between researchers coming from different schools and pursuing different approaches to unilateral problems in Mechanics and Engineering. The success of the first meeting induced us to organize a second one, with a more formal structure and with a larger participation. In that occasion, the discussion was very lively and fruitful, and the idea came of transforming the presented contributions into written communications, and of collecting them in a volume of Proceedings. The volume appeared in 1985, and became soon a reference book for researchers working in the area. The same formula was adoptedfor the third meeting. Once again, the publication ofthe proceedings was decided at the end of the meeting, and this explains in part the delay in the issue ofthe present book. The communications collected here deal, mainly with developments of subjects already treated in the first volume, such as unilateral contact with friction, adhesion, and dynamical effects, or unilateral internal constraints and non-convex constitutive equations. In part, they deal with new topics, such as unilateral analytical mechanics and probabilistic approach to structural analysis in the presence of unilateral constraints. A look at the contents of this Volume puts in evidence that for a good part of the topics a firm theoretical ground has been reached. For them, the interest shifts to the development of appropriate solution techniques. On the other hand, there are subjects for which the theoretical formulation is not yet satisfactory. In both cases, there is still much work to be done, and the whole area seems to be in a fast evolution. This is confirmed by the success of
other recent meetings, as the /SIM M minisymposium on Unilateral Problems in Mechanics, held
