Quasi-static analysis of viscoplastic plates by the boundary element methodQuasi-static analysis of viscoplastic plates by the boundary element method Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-10-171993enA direct boundary element method (BEM) is developed for the determination of the time-dependent inelastic deflection of plates of arbitrary planform and under arbitrary boundary conditions to general lateral loading history. The governing differential equation is the nonhomogeneous biharmonic equation for the rate of small transverse deflection. The boundary integral formulation is derived by using a combination of the BEM and finite element methodology. The plate material is modelled as elastic-viscoplastic. Numerical examples for sample problems are presented to illustrate the method and to demonstrate its meritshttp://creativecommons.org/licenses/by/4.0/Engineering Analysis with Boundary Elements411265-268 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
