| Abstract: | An automated approach for the analysis of plates on an elastic foundation is presented. The approach combines automatic mesh generation with nonlinear analysis to analyse plates of arbitrary shape on an elastic foundation subject to uplift. Two separate complete systems are presented, the first employing an ACM element to analyse rectangularly-shaped plates and the second employing a heterosis element to analyse plates of arbitrary shape. Solutions of the systems are presented and compared to theoretical results. A convergence study is also presented. |
