Abstract: An extremum principle of Lee and Martin [2], for mode form solutions of a structure deforming plastically as result of dynamic loading, is discussed with special reference to conditions for ...

Abstract: Large deflections of a clamped circular plate subjected to axially symmetric impulsive loading are obtained by means of the mode approximation technique. The mode shapes and accelerations are ...

Abstract: The experimental techniques and the results obtained in a program to evaluate the assumptions of dynamic, rigid-plastic theory of beams are presented. The experiments used steel and aluminum-alloy ...

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: Calculations of two types of fractal dimension are reported, regarding the elastic-plastic response of a two-degree-of-freedom beam model to short pulse loading. The first is Mandelbrot’s (1982) ...

Abstract: Hohenemser and Prager [1] proposed a constitutive law for a solid of Bingham type We use a form of this law to study some cases of longitudinal impact on a bar causing large plastic strains. ...

Abstract: In a particular example of short pulse loading on a pin-ended beam, the permanent deflection is predicted by a numerical solution to be in the direction opposite that of the load. Analysis ...
