Abstract: Parametric coupling that arises under certain conditions of excitation has been analyzed in an electrical R-L-C circuit that is coupled with a mechanical system through a nonlinear inductance. ...

Abstract: Similitude theory is used to develop scale models for determining the earthquake response of pile foundations embedded in overconsolidated clay. The model is compared with full-scale foundations ...

Abstract: The sloshing of liquids in tanks that use a flexible, inextensible bladder to contain the liquid is investigated experimentally and theoretically. The bladder affects both the configuration of ...

Abstract: The response of a model helicopter rotor blade to random excitation while in simulated forward flight is studied analytically and experimentally by means of an electromechanical apparatus. ...

Abstract: Since its introduction a few years ago the use of the power/response spectrum transformation has gained considerable interest and acceptance, and a number of new applications of the transformation ...

Abstract: Qualification of nuclear plant equipment and components can be performed by analysis, test, or a combination of both. It is often required to synthesize artificial time histories which represent ...

Abstract: A general methodology has been developed for correlating the severity of various seismic qualification motions that can have very different dynamic characteristics. The approach is based on a ...

Abstract: Requalification of equipment in operating nuclear power plants to present-day criteria can be an expensive undertaking; however in situ measurements and data analysis procedures can be used to ...

Abstract: Some experimental data, primarily on total force response, are presented for nonlinear lateral sloshing in rigid tanks of various geometries. Some effect of excitation amplitude on liquid swirl ...

Abstract: Similitude theory is used to develop a scale model for determining the dynamic response properties of a single pile embedded in over-consolidated clay. The basis for the design is a full-scale ...
