The first term refers either to the homogeneity (A/ = 1, deformed volume fraction being 100%) or to the heterogeneity (Af 0) of the deformation. The second term follows free-volume theory and takes into account the glass fragility, that is, the viscosity-temperature deviation from the Arrhenius law (Chapter 6). This term is a constant at a given temperature (constant free volume) unless elevated stresses allow for increasing free volume within the material. This in... 

Solids by solvents. The various forms of Soxhlet apparatus illus trated in Section 11,44 can be purchased with ground glass joints. A simplified form, in which the fragile side tubes are absent, is shown in Fig. II, 58, 1. The material to be extracted, if of granular form, may rest upon a sintered glass disc or upon a removable septum ... 

The type of material to be used depends very largely on whether coating is carried out mechanically or by hand. For hand application it is not possible to use comparatively fragile staple tissues made of glass or asbestos and it is necessary to use a strong open-mesh fabric, such as woven asbestos or woven glass. The woven wraps are a great deal more expensive than the staple tissues, which are mechanically applied. 

But carbon and glass fibers are notable for their fragility and are inconvenient for processing and, therefore metal fibers of brass (Aron Kasei Co.), copper (Toshiba Chemical Corp.) [14], stainless steel (Brunswick Corp., Bekaert) [16], aluminium (MB ASSOCIATES, TRANSMET) [15] have been introduced.
