The behaviour of unidirectional 45 °, angle-ply ± 45 ° and multidirectional [±45 °,0 °]s fibreglass/epoxy laminates at room temperature under tensile and fatigue loadings has been investigated. Results for angle-ply ± 45 ° laminates show that the rate/frequency effect is significant in both tensile and fatigue loadings. In the case of tensile loading tests, the rate effect was observed in the stress-strain response. Fatigue data indicate a considerable accumulated cyclic creep which depends on the loading condition, i.e. applied load and frequency. The effect of frequency on the fatigue life is explained in terms of cyclic creep and its detrimental influence on the fatigue resistance. In contrast, laminates made of 45 ° unidirectional and multidirectional [± 45 °,0 °]s show very little frequency effects. 相似文献

Water spray is a highly effective fire-protection agent, because evaporating droplets extract energy from the flame and combustion products as well as attenuate thermal radiation by absorption and scattering. The main objective of this paper is to characterize radiative transfer in a homogeneous water spray curtain (layer) and to calculate spectral transmittances and absorptances of a curtain. The spectral and total absorptances and transmittances reported in the paper provide fundamental understanding of radiation attenuation by water curtains. The empirical equation developed for the scaled spectral extinction coefficient of water sprays may be useful for modeling radiative transfer in spray curtains using CFD. Since the spray acts as a shield that attenuates radiation such global radiation characteristics can readily be used in simple, preliminary design analyses for mitigating and controlling fires. 相似文献
