Abstract: The Frahm-type dynamic vibration absorber is analyzed for the case where both main and absorber springs have nonlinearities of the Duffing type. A one-term-approximation solution is assumed for ...

Abstract: A new numerical search algorithm is presented which is employed to determine optimum shapes for pin-ended columns having elastic behavior. The search algorithm utilizes a gradient search scheme ...

Abstract: The beam on elastic foundation is employed as a mathematical model to develop an explanation for the crawling phenomena observed for the rails used to support the rotating beds of large rotary ...

Abstract: In-situ recovery methods for many of our hydrocarbon and mineral resources depend on the ability to create or enhance permeability in the resource bed to allow uniform and predictable flow. ...
