Abstract: A common practice to uncouple drill steels in percussive rock drilling is by rattling. Rattling is primarily a continuation of a drilling process without the rotation of the drill steels. By ...

Abstract: This paper deals with asymptotic stability of an analytically derived, synchronous as well as nonsynchronous, steady-state solution of an impact system which exhibits piecewise linear characteristics ...

Abstract: This paper describes an extended de Vogelaere method which can be used to integrate numerically the equations of motion arising from a finite-element analysis. The method has a truncation error ...

Abstract: In the study of steady-state solutions of a nonlinear, or piecewise linear dynamic system under periodic forcing, it is often necessary to examine the stability of the solutions. The reason ...

Abstract: This paper deals with the stability of motion of an elastically suspended vibrating hammer that impacts upon an energy absorbing surface. The energy absorber could represent, for example, a ...

Abstract: Vibrating plate soil compactors are widely used in building and road construction, yet no adequate dynamic theory exists to predict vital performance characteristics such as frequency of impacts, ...

Abstract: A practical approach to the distortional analysis of steel box girders is presented herein. The EBEF (equivalent beam on elastic foundation) method is an enhancement of the BEF (beam on elastic foundation) method, which ...
