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: This study was initiated after the sliding plate expansion joints of Millard E. Tydings Memorial Bridge, a long-span truss bridge, failed prematurely just a few months after their initial installation. The study included ...

Abstract: Condition-ratings in bridges have been used by the Federal Highway Administration as a way to classify structural deficiencies and structures that are functionally obsolete. These ratings are determined by evaluating the ...

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: The softened truss model theory applied to a prestressed concrete multiple cell box is developed in this study. In this theory, the concrete torsional problem is solved by combining equilibrium and compatibility conditions ...
