“…This indicates that the energy dissipation increases with both increasing  0 and ω, or with the strain rate    0 0   , characteristics of the viscous behavior. Increase in dissipation with  0 was also reported in literature for filled elastomers [94,95] , whereas the dependence on ω is rarely reported. In the present study, the intra-cycle dissipation was generally small.…”

Linear and nonlinear viscoelasticity of gelatin solutions was investigated by rheology. The dynamic mechanical properties during the sol-gel transition of gelatin followed the time-cure superposition. The fractal dimension d f of the critical gel was estimated as 1.76, which indicated a loose network. A high sol fraction w s = 0.61 was evaluated from the plateau modulus by semi-empirical models. Strain-stiffening behavior was observed under large amplitude oscillatory shear (LAOS) for the gelatin gel. The strain and frequency dependence of the minimum strain modulus G M , energy dissipation E d , and nonlinear viscoelastic parameter N E was illustrated in Pipkin diagrams and explained by the strain induced helix formation reported previously by others. The BST model described the strain-stiffening behavior of gelatin gel quite well, whereas the Gent and worm-like chain network models overestimated the strain-stiffening at large strains.

“…Single d.o.f. models have been examined to describe the non-linear sti!ness and damping characteristics where two di!erent approaches were discussed, one for modelling the hysteresis loops and another for modelling the transmissibility functions [18]. Also, an alternating time}frequency identi"cation technique has been developed [19] based on the Bouc}Wen model [20].…”

“…In order to resolve this problem, isolators with nonlinear damping have deserved more attention from researchers for years [2][3][4][5][6][7][8][9]. This is because all isolators in vibration systems are inherently nonlinear [1,2], and the nonlinear damping has the potential in proving the isolator performance at both the resonance and the higher frequencies.…”

In this paper, vibration isolator of single degree of freedom systems having a nonlinear viscous damping is studied under force excitation. Stability of the steady state periodic response has been discussed. The influence of damping coefficients on the force transmissibility and displacement transmissibility is investigated. The relationship between amplitude and frequency is derived by using the averaging method. Results reveal that the performance of the nonlinear isolator has some beneficial effects compared with linear isolator in a certain range. Numerical simulations are presented to illustrate the results.
