Dynamic Modeling and Analysis of Centrifugally Stiffened Proportionally Damped Timoshenko Beam

ObjectivesTo study the effect of proportional damping on the dynamic response of centrifugally stiffened Timoshenko beam.MethodsA novel method has been successfully developed to model and analyze the forced damped response of centrifugally stiffened Timoshenko beam. The method uses a single beam element with six physical nodal coordinates. The transverse displacement and rotation of the beam are described using a mixture of polynomial and enriching trigonometric shape functions. The damping matrix is incorporated into the equations of motion (EOM) according to Rayleigh assumption. The damped EOM are expressed in state space form.ResultsThe dynamic characteristics for the rotating forced damped vibration of Timoshenko beam are analyzed by assuming modal damping ratios for the first two modes and then finding the constants for the proportional damping. The EOM are integrated …

Free Vibration Frequencies of a Variable Cross-Section Timoshenko-Ehrenfest Beam using Fourier-p Element

An efficient method has been developed to analyze the natural frequencies of a Timoshenko-Ehrenfest beam with variable cross-sections undergoing free flexural vibration. The method uses a single element to discretize the beam and combines polynomial and trigonometric shape functions to represent the displacement fields, with the trigonometric shape functions representing the internal degrees of freedom (DOF) of the beam. By incorporating trigonometric shape functions as enriching functions alongside polynomials, the potential issues related to ill-conditioning associated with higher-order polynomials are avoided. The differential equations of motion for the free vibration are derived using Lagrange’s equation. The generalized eigenvalue problem is then formulated. Non-dimensional natural frequencies are computed considering different parameter variations such as taper ratios, shear deformation, rotary …

Combined influence of rotary inertia and shear coefficient on flexural frequencies of Timoshenko beam: numerical experiments

When dealing with the computation of bending frequencies for Timoshenko beams, it is common practice to assume a constant shear coefficient for a specific cross-sectional shape of the beam within the plane of bending vibration being considered. However, there have been various definitions, interpretations, and values assigned to it, depending on static and dynamic considerations, as well as experimental investigations, regardless of whether a wave approach or a mode approach is utilized. Currently, there is a lack of unanimity regarding the most suitable value for the shear coefficient. This study examines the impact of varying both the shear coefficient and the rotary inertia parameter on the first four bending modes of a uniform Timoshenko beam, considering numerous boundary conditions. The present numerical experiments reveal that increasing the shear coefficient tends to increase the frequency …

Hybrid Friction Diffusion Bonding of Tube–Tubesheet Joint: A finite Element Model

A three-dimensional finite element model for hybrid friction diffusion bonding of tube–tubesheet joints is developed based on coupled Eulerian–Lagrangian technique. The investigation is aimed to study the effect of process parameters on temperature and pressure buildup in addition to material flow during the process. Temperature-dependent material properties were utilized in addition to Johnson–Cook material flow-stress model to describe the material behavior, while modified Coulomb’s frictional model was used to govern the contact between the tool and the workpiece. The numerical findings show good agreement with early experimental results. Lower tool rotational speed and longer welding time may lead to uniform tube deformation. Estimated temperatures and pressures could serve as key indicators for the diffusion bonding to take place or not.
