... boundaries are represented by distributed translational and torsional springs. In the Chebyshev collocation method, the convergence studies are performed to determine the sufficient number of the grid points used. In the perturbation method, the small perturbation parameter is defined in terms of the damage...

...S. A. Fazelzadeh; A. Mazidi This paper deals with the nonlinear aeroelastic behaviors of bending-torsion wings subjected to a transverse follower force. The nonlinear structural wing formulation is based on von Karman large deformation theory. In order to accurately consider the spanwise location...

...Olivier A. Bauchau; Leihong Li; Pierangelo Masarati; Marco Morandini Flexible joints, sometimes called bushing elements or force elements, are found in all multibody dynamics codes. In their simplest form, flexible joints simply consist of sets of three linear and three torsional springs placed...

... length according to its base-pair sequence. Examples of “sequence-dependent” material properties include the stress-free curvature and the stiffness for bending and torsion. Quantifying and separating these sequence-dependent properties from experimental data remains a significant challenge as they often...

...Sergey A. Voronov; Alexander M. Gouskov; Alexey S. Kvashnin; Eric A. Butcher; S. C. Sinha The nonlinear dynamics of a tool commonly employed in deep hole drilling is analyzed. The tool is modeled as a two-degree of freedom system that vibrates in the axial and torsional directions as a result...

...Steven W. Shaw; Peter M. Schmitz; Alan G. Haddow This paper describes an analytical and experimental investigation of the dynamic response and performance of a special type of centrifugal pendulum vibration absorber used for reducing torsional vibrations in rotating systems. This absorber has...
