Comparison of boundary element and finite element methods for dynamic analysis of elastoplastic platesComparison of boundary element and finite element methods for dynamic analysis of elastoplastic plates Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-171999enBoundary and finite element methodologies for the determination of the response of inelastic plates are compared and critically discussed. Flexural dynamic plate bending problems are considered and a hardening elastoplastic constitutive model is used to describe material behaviour. The domain/boundary element methodology using linear boundary and quadratic interior elements and the finite element method with quadratic Mindlin plate elements are used in this work. The discretized equations of motion in both methodologies are solved by an efficient step-by-step time integration algorithm. Numerical results obtained are presented and compared in order to access the accuracy and computational efficiency of the two methods. In order to make the comparison as meaningful as possible, boundary and finite element computer codes developed by the author are used in this paper. In general, boundary elements appear to be a better choice than finite elements with respect to computational efficiency for the same level of accuracy.http://creativecommons.org/licenses/by/4.0/Advances in Engineering Software530353–360 Providakis Konstantinos Προβιδακης Κωνσταντινος Elsevier Building damage prevention Building protection Buildings--Damage prevention Protection of buildings buildings protection building damage prevention building protection buildings damage prevention protection of buildings
