Abstract: Elastic, perfectly plastic structures are considered under the action of repeated short-duration exitations of seismic type acting in an unknown time sequence, but belonging to a given polyhedral excitation domain. The ...

Abstract: Elastic-plastic rate-independent materials with isotropic hardening/softening of nonlocal nature are considered in the context of small displacements and strains. A suitable thermodynamic framework ...

Abstract: In beams with full-end constraints, loaded transversely by short pressure pulses, the effect of extensional plastic deformation is to make possible instabilities related to snap buckling in the ...

Abstract: The paper summarizes recent results on the unexpectedly critical role played by damping in the class of problems where pulse loading may lead to anomalous final displacements, i.e., opposite to the direction of loading. ...

Abstract: The paper discusses chaotic response behavior of a beam model whose ends are fixed, so that shallow arch action prevails after moderate plastic straining has occurred due to a short pulse of ...
