BEM-FEM comparison studies for the inelastic dynamic analysis of thick plates on elastic foundationsBEM-FEM comparison studies for the inelastic dynamic analysis of thick plates on elastic foundations Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-172000enBoundary and Finite Element methodologies for the determination of the inelastic response of thick plates resting on Winkler-type elastic foundations are compared and critically discussed. For comparison reasons the domain/boundary element and the finite element methodology use isoparametric elements of the same accuracy level. After a discretizaton of the integral equations of motion in both methodologies an efficient step-by-step time integration algorithm is used to solve the resulting matrix equations. Comparison studies are shown for impacted elastoplastic thick plates with smooth boundaries and supported on different Winkler-type foundations. The numerical results reveal that boundary element method appears to be a better choice in modelling the plate-foundation interaction.http://creativecommons.org/licenses/by/4.0/Computer Modeling in Engineering and Science31123-130 Providakis Konstantinos Προβιδακης Κωνσταντινος Building damage prevention Building protection Buildings--Damage prevention Protection of buildings buildings protection building damage prevention building protection buildings damage prevention protection of buildings
