TL;DR: In this paper, a detailed comparison of the predicted eigenfrequencies of twisted rotating plates as obtained by using two different shape functions is presented, and results of a brief study of cambered plates are presented.
TL;DR: In this article, a theoretical analysis of the response characteristics of the Stockbridge dampers is presented, and the experimental results of the analysis have been verified experimentally by treating it as a two-degree-of-freedom system.
TL;DR: In this article, an experimental investigation carried out on square and rectangular plates with various boundary conditions to determine the damping ratios for a few modes of vibration is reported, based on the experimental findings, the Rayleigh damping coefficients can be computed for subsequent use in the modal superposition technique.
TL;DR: In this paper, the structural dynamic characteristics of a composite beam are analyzed and the results of the analysis are compared with those available in the literature, based on the comparison, the influence of the warping function in defining the coupling terms in the modulus approach and also on the natural frequencies of the beam has been identified.
TL;DR: In this article, a finite element technique has been used to determine the natural frequencies of a pre-twisted and tapered plate mounted on the periphery of a rotating disc, which is idealized as an assemblage of three noded triangular shell elements with six degrees of freedom at each node.
TL;DR: In this article, a review article provides an overview of the problems pertaining to structural dynamics with bolted joints, including energy dissipation, dynamic properties of the joints, parameter uncertainties and relaxation, and active control of the joint preload.
TL;DR: In this paper, the authors proposed a modified geometry of an asymmetric spur gear drive designed as a combination of an involute gear and a double crowned pinion that enables to localize and stabilize the bearing contact and obtain a favorable shape of transmission errors.
TL;DR: In this paper, the authors review most of the research done in recent years (1989-2012) on the vibration analysis of composite beams, with emphasis given to the theory being applied (thin, thick, layerwise), methods for solving equations (finite element analysis, differential transform and others) experimental methods, smart beams (piezoelectric or shape memory), complicating effects in both material and structure, and other areas that have been considered in research.
TL;DR: In this paper, a bibliographical review of finite element methods applied for the analysis of fastening and joining from the theoretical as well as practical points of view is given, which are classified in the following categories: pin joints; thread connections; bolted joints, screws, nuts, rivets; fittings; tubular joints; expansion joints; gaskets; and other types of fasteners.
