Craze initiation in glassy polymers
In this work a method is presented that can be used to predict craze initiation in glassy polymers. The approach is based on the view that the development of a craze is preceded by de formation of a localised plastic deformation zone. As this zone develops, the hydrostatic stress increases, and, when exceeding a critical stress level, cavitation will take place, leading to local development of ...
متن کاملCraze-Initiation Kinetics in Polystyrene
In this study it is shown, for a commercial polystyrene grade, that the strain-rate dependence of craze initiation is equivalent to that of yielding. This implies that the kinetics of craze initiation are determined by the nonlinear flow behavior, and that the actual cavitation process is governed by an additional, apparently rateindependent, criterion. © 2004 Wiley Periodicals, Inc.

متن کاملChasing the Craze: When the Right Variables are Off-Stage
A smooth white glaze, (Figure 1) with a buttery surface and smooth breaking on edges, just enough change of whiteness in a crevice pooling, seemingly opaque when thicker, but with a certain glow, a slight grey showing through. It crazes slightly, a fine webbing of cracks. Not enough to be decorative crazing, and not enough crazing to make me abandon the glaze, but enough crazing that I would li...

15 صفحه اولGene Transfer: Gene Swapping Craze Reaches Eukaryotes
Recent studies have provided evidence for gene transfers from prokaryotes to eukaryotes and between eukaryotes. The mechanisms and frequencies of these transfers remain the subject of speculation, but the findings provide ample reason to seriously consider interspecies gene transfer as an important evolutionary process in eukaryotes.
