Abstract: Instantaneous mode responses of dynamically loaded elastic, viscous, ideally plastic and rigid, viscoplastic structures are defined and characterized by variational criteria with isometric constraints. ...

Abstract: Vibrations of an intermediately supported U-bend tube fall into two independent classes as an incomplete ring of single span does, namely, the in-plane vibration and the coupled twist-bending ...

Abstract: A unified method of approximating the response of rigid-plastic and elastic, perfectly plastic beams subjected to impulsive loading is described. The method is based on the uniqueness proof for ...

Abstract: Presented here is a nonlinear analysis of infinite plates and shallow shells, subjected to doubly periodic surface loadings. The drastically different behaviors predicted by the linear and the ...

Abstract: Given in this paper is a nonlinear analysis of snap-through problems of shallow arches on linear elastic foundations subjected to time-varying loads which have a time-independent character as τ ...

Abstract: Composite beams comprised of concrete slabs and steel beams joined by mechanical shear connectors are commonly used in modern building design. The use of innovative deconstructable high-strength friction-grip bolt (HSFGB) ...

Abstract: A rigid mass driven by Coulomb friction from a randomly moving foundation is used as a simple model of a possible earthquake isolation system for a stiff compact structure. The structure is ...
