... this bifurcation instability. Here, a dynamic stiffness evaluating method is presented for assessing the threshold of the period-doubling and complex motions in VC primary resonances of ball bearings, where the elaborate evolution of the bifurcating process is obtained by harmonic balance and alternating frequency...

... of nanorods is performed. SFE formulation is carried out and the exact shape functions (frequency dependent) and dynamic stiffness matrix are obtained as function of nonlocal scale parameter. It has been found that the small scale affects the exact shape functions and the elements of the dynamic stiffness...

... the dynamic stiffness of rubber isolators in working conditions, where various amplitudes may be found in a frequency range. A short description of the different parts of this mechanical model is given below. The basis of fractional-derivative technique for linear viscoelasticity is to use...
