Hysteresis energy is that energy used per cycle of operation to overcome the effect of hysteresis. [Pg.817]

Because of hysteresis, energy is dissipated as heat in a magnetic material as it is taken round a complete B-H loop, and the hysteresis energy loss Wh per unit volume of material is [Pg.485]

Mechanism of the Great Hysteresis Energy of Carbon Black-Filled Rubber [Pg.537]

FIGURE 18.20 Relation between input energy and hysteresis energy at break for HAF carbon-filled and unfilled styrene-butadiene rubber (SBR). (From Payne, A.R., J. Polymer, Sci., 48, 169, 1974.) [Pg.538]

Equation (12.18) establishes that the hysteresis energy, the energy associated with the area in the hysteresis region of an intrusion-extrusion cycle, is given by [Pg.128]

Influence of strain rate on Mullins effect and hysteresis energy loss [Pg.127]

As is well known, there is a close relation between the input energy at break, Ub and the hysteresis energy at break, Hb, for many kinds of filled and unfilled rubber vulcanizates, given by the following empirical Equation 18.2 [Pg.537]

Equation 18.2 reveals the importance of energy dissipation in the fracmre of mbbery materials, that is, the strength of rubbers, whether filled or unfilled, is governed by the hysteresis energy dissipated in deforming the system. [Pg.537]

In Fig. 23a, the hysteresis energies (I/hys) calculated from the cycles in Fig. 22a are plotted against the maximum strain in terms of uniaxial (/Imax) and biaxial (Abiax nax) extension ratios. All C/bys data collapse onto a single curve hence, the hysteresis energy only depends on the maximum extension of the polymer chains. [Pg.130]

We indicated all relative quantities by asterisks. Thus we defined the relative first cycle residual strain, and relative first cycle hysteresis energy dissipation by [Pg.122]

Thus, the expression for the pore potential is identical to the pressure-volume work differences between intrusion and extrusion and can be expressed as the hysteresis energy, i.e. [Pg.129]

FE simulations of the stress-strain properties of fiUer-reinforced elastomers are an important tool for predicting the service live performance of mbber goods. Typical examples are the evaluation of rolling resistance of tires due to hysteresis energy losses, mainly in the tire tread or the adjustment of engine mounts in automotive applications. [Pg.622]
