The phenomenon can be described by a viscous damping
A comparison is made between Bingham plastic and Bingham bi-plastic force responses to constant velocity input, and equivalent viscous damping
is examined with respect to non-dimensional parameters.
The viscous damping
coefficient of the coffee fruit-stem system was calculated by Equation 4.
22kN/mm at a displacement of [+ or -] 130 mm, corresponding to a shear strain of 100% and equivalent viscous damping
of about 15%.
The main material of the viscous damper is silicone, which can provide full viscous damping
energy, and the equivalent damping ratio level can reach 0.
A three-fold difference with orientation was seen in the viscous damping
As mentioned above, comparative issue of energy dissipation and ratio of equivalent viscous damping
in different states of wall crater has not been studied clearly.
The main purpose of the conducted experiments was to obtain the hysteretic response, as it contains the information on stiffness degradation, strength deterioration, viscous damping
and energy dissipation capacity.

ABSTRACT: In this paper, results of an experimental study to investigate the equivalent viscous damping
(EVD) of the concrete reinforced with metallic fibers in mono and hybrid form have been presented.
005 viscous damping
, 3000 rpm reference speed, 4 poles and trapezoidal back EMF wave form.
The effect of geometry and extent of gravity load on various parameters used to quantify seismic performance such as equivalent viscous damping
for evaluating energy dissipation capacity, ultimate ductility and drift ratio of the walls is examined and discussed.
