Abstract: Localized and global, of eigenmode type, initial geometric imperfections were superimposed on perfect torispherical, ellipsoidal, and toroidal shells of circular and elliptical cross section. Reduction ...

Abstract: Track irregularity is considerably important in track-vehicle studies. Recorded data of these irregularities form a basis to develop track standards. This also helps specify track inputs to the vehicles. In this paper ...

Abstract: Dynamic analysis of a railway track under moving vibratory masses is presented in this technical note. In such problems the critical velocity is an important parameter. This is influenced by the dynamical characteristics ...
