Prefatigue hysteresis effects on viscoelastic crack-propagation velocity were investigated through velocity-gauge techniques at different temperature levels. It was found that prefatigue effects accelerate elastic predominance in viscoelastic dynamic crack propagation, approaching elastic brittle fr

Examination of pure nickel with grain sizes irom 0.12 to 130 jun showed that ant:; rhe large grain sizes exhibited stress-strain curves which agreed with a Taylor-corrected [I 1 i] single LTstal curve. Work hardening was found nearly independent of grain size for sizes below I pm. These data were fi
## Abstract The effects of maize (__Zea mays__ L) grain hardness, morphological factors (grain size and shape), drying rate and the development of stress cracking over time were investigated for four hybrids (Hmv565βββ3βΓβE1386, CF06, CF05 and Furio). The reβparametrised MorganβMercerβFlodin (MMF)
