Hysteresis and energy loss in flexible polyurethane foams,ans in practical terms that we are dealing with a highly non-linear static and dynamic mechanical situation. This is manifest by the fact that under high intensity harmonic excitation a flexible foam-based vibration isolating system exhibits behaviour similar to that of classical chaos [1].作者: 飛來飛去真休 時間: 2025-3-22 09:35
Heat transfer in foams, made of the same material. In this chapter the foam conductivity refers to the effective value exhibited by the foam. It is the ratio of the rate of heat transfer per unit cross-sectional area to the applied temperature difference.作者: exhibit 時間: 2025-3-22 14:57 作者: AXIOM 時間: 2025-3-22 20:37 作者: gangrene 時間: 2025-3-23 00:22

The morphology of flexible polyurethane matrix polymers,d in Fig 4.2. The reaction products, which include urethanes, ureas, amides, allophanates, biurets, carbodiimides and isocyanurates, subsequently associate to generate an auxiliary network. The latter associations generally lead to a polymer having multiphase molecular morphology.作者: 因無茶而冷淡 時間: 2025-3-24 09:38

Impact response,within the cells provides pneumatic cushioning, which happens to be of the correct magnitude for many applications. Open cell foams, which have been discussed in Chapter 8, do not have this energy absorption mechanism, although there may be pneumatic losses as the air passes through restricted holes作者: 個人長篇演說 時間: 2025-3-24 17:45

Thermal ageing,on-encapsulated foam tends to increase with time due to an effusion of the blowing agents and an infusion of air. This causes the gas composition in the foam cells to change with time. As air has a higher thermal conductivity than the blowing agents a thermal ageing occurs. Essentially, the mechanis作者: Extort 時間: 2025-3-27 20:43

Hysteresis and energy loss in flexible polyurethane foams, are the main functional attributes, is governed by two material properties: the effective stiffness; and energy lost through hysteresis under the conditions that prevail in use.
