Semianalytical structural analysis based on combined application of finite element method and discrete-continual finite element method Part 4: Verification samples

摘要

This paper is devoted to so-called semianalytical plate analysis, based on combined application of finite element method (FEM) [1,2] and discrete-continual finite element method (DCFEM) [3-11]. Verification samples of deep beam analysis and plate analysis are under consideration. ANSYS Mechanical 15.0 (finite element method (FEM) [12-18]) was used for verification purposes. We can conclude that the results of analysis obtained by the ANSYS Mechanical and CSASA2D generally agree well with each other. DCFEM is more effective in the most critical, vital, potentially dangerous areas of structure in terms of fracture (areas of the so-called edge effects), where some components of solution are rapidly changing functions and their rate of change in many cases can't be adequately taken into account by the standard FEM.
