Abstract

In this article a non-linear BEM formulation do deal with elastoplastic analysis of plates in bending is presented. The classical Kirchhoff s hypothesis is taken to derive the displacement, bending moment and shear force integral equations where fields of initial values are considered to model non-linear behaviors. A particular elastoplastic model, suitable to simulate concrete behavior, is adopted for slab analysis. Introduction BEM formulations have already been proposed to deal with an enormous number of complex engineering problems, many of them exhibiting non-linear behaviour. To deal with two-dimensional elastoplastic problems Telles and Brebbia [1], in 1980, have proposed an efficient scheme. For elastoplastic plate bending analysis we can mention the work due to Moshaiov & Vorus [2], who have implemented a particular increment
