It is well known that the presence of the delamination in a composite laminated beam (CLB) introduces a local flexibility which changes the dynamic characteristics of the structure. The finite element method is used for modelling the CLB to obtain the effect of the delamination length and its starti

β¦ Synopsis
In this paper the natural frequencies of composite tubular shafts have been analysed. Equivalent modulus beam theory (EMBT) with shear deformation, rotary inertia and gyroscopic effects has been modified and used for the analysis. The modifications take into account effects of stacking sequence and different coupling mechanisms present in composite materials. Results obtained have been compared with that available in the literature using different modelling. The close agreement in the results obtained clearly show that, in spite of its simplicity, modified EMBT can be used effectively for rotordynamic analysis of tubular composite shafts.

Vibration problems of spinning shafts with attached disks occur quite frequently, but until recently the analyses were generally restricted to the Β―exible-shaft/rigid-disk models, which lost at least two-thirds of the vibrational characteristics to a certain extent. In the present paper, a substruct
Fast filling of hydrogen pressure tank leads to thermomechanical stresses in vessel structure. In this paper, the aim is to study the thermomechanical behaviour of the material used in the vessel structure. Flat coupons made of the same constituents as the hydrogen tank materials and with different
## Abstract This paper deals with the combined influences of the vibrational parameters chosen as the material types, number of active turns, helix pitch angle, minimum to maximum radii of the cylinder and maximum cylinder to wire diameters on the first six resonance frequencies of unidirectional c
