Reduction of Dynamic Cable Stiffness to Linear Matrix Polynomial [PDF]
Journal of Engineering Mechanics, 1993 For the dynamic stiffness of a sagging cable subject to harmonic boundary displacements, frequency-dependent closed-form analytic functions can be derived from the corresponding continuum equations. When considering such functions in stiffness matrices of composed structures, however, these matrices become frequency dependent, too - a troublesome fact,

Dynamic Stiffness Matrix of Sagging Cable [PDF]
Journal of Engineering Mechanics, 1991 The dynamic behavior of an extensible sagging cable is investigated. A dynamic stiffness matrix is presented whose coefficients are functions of the frequency of motion, and that is suitable for dynamic direct-stiffness analysis of composed systems such as cable-stayed bridges and guyed masts.

Dynamic stiffness matrix of a rectangular plate for the general case [PDF]
Journal of Sound and Vibration, 2015 The dynamic stiffness matrix of a rectangular plate for the most general case is developed by solving the biharmonic equation and finally casting the solution in terms of the force-displacement relationship of the freely vibrating plate. Essentially the frequency dependent dynamic stiffness matrix of the plate when all its sides are free is derived ...

Frequency dependent mass and stiffness matrices of bar and beam elements and their equivalency with the dynamic stiffness matrix [PDF]
Computers & Structures, 2021 Starting from the solutions of the governing differential equations of motion in free vibration, the frequency dependent mass and stiffness matrices of bar and beam elements have been derived in this paper, but importantly, their equivalency with the corresponding dynamic stiffness matrix is established.
