Craze-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 کاملUltrasonic Measurement of Particle Concentration in Polystyrene/glass Beads Composites by a Differential Scheme
The attenuation spectra obtained from ultrasonic measurement is applied to estimate the particle concentration in general purpose polystyrene (GPPS) /GB (glass beads) composites by a differential scheme. Composite samples with particle radium 80 μm are tested at five volume fractions ranging from 6 % to 40 %. The longitudinal attenuation characteristics of these samples are found to depend mark...
متن کاملThe Melt Shear Viscosity of Polypropylene/Glass Bead Composites at High Extrusion Flow Rates
The effects of filler content and its surface treatment with silane coupling agent on the melt shear viscosity of glass bead-filled polypropylene (PP) composites have been investigated using a capillary rheometer at a wide shear rate scope of 150 to 7200 s and temperature range of 160 to 200 C. The melt flow obeys power law, but the slopes of the flow curves have transitions at the shear rate o...

15 صفحه اولIn-situ observation of formation of Si clathrates
Introduction Type-I Si clathrates, whose general chemical formula is A8Si46, have a unique structure. In the compounds, Si atoms form Si20 dodecahedra and Si24 tetrakaidehedra, and these polyhedra are linked by shared faces. The A atoms are located in the center of the polyhedra. A search on the superconducting materials has been conducted in Si clathrates since discovery of superconducting ful...
