A REFINED THEORY OF MODERATELY THICK PLATES ACCORDING TO EXPOSITION OF THE CLASSICAL TECHNICAL THEORIES THEORETICAL ASPECTS

摘要

In this paper we propose a new refined shear deformation plate theory. This theory possesses a series of desirable features, the most salient of which areas follows: (i) The loads, which are usually considered to be applied on the middle surface of the plate, are applied in this new theory on the top surface of the plate; (ii) The equations deduced provide the same order of accuracy as several theories with second order shear deformation effects; (iii) It constitutes a theory, in the sense defined by Love, since it gives easy expressions for application to problems in different fields in architecture and engineering.
