A computationally efficient numerical model for a dynamic analysis of thin plates based on the combined finite–discrete element method

Abstract

This paper presents a new numerical model for a static and dynamic analysis of thin plate structures based on the combined finite–discrete element method (FDEM). The model uses three-noded triangular finite elements taking into account linear-elastic material behaviour, finite rotations, finite displacements and small strains. The model is implemented into the open source FDEM package ‘Yfdem’. Performance of the new numerical model was demonstrated on simple benchmark tests by a comparison with known analytical and numerical results.
