Voluminal deformation

A calculation corresponding to that of equations 10 and 12 will provide the time dependence of pressure following a sudden voluminal deformation. For this purpose, the voluminal strain may be defined as the relative change in volume,...

Alternatively, in the bulk analog of a creep experiment, the pressure is maintained constant and the decrease in volume is followed with time. Apparatus for very precise measurements at moderate pressures has been described by Goldbach and Rehage the volume change is measured by. motion of mercury in a capillary. Other devices, suitable for higher pressures, have been used by Mandelkern and by Findley, who measured voluminal deformation by strain gauges. 

It can be seen that the bulge was caused by the formation of a white corrosion product on the outer surface of the aluminum extrusion. This voluminous material, trapped between the copper and the aluminum, exerted pressure on the relatively soft copper sheet, causing it to deform. 

From the consumer s standpoint, body is associated with fullness, volume, springiness, and bounce. Clarke et al. [188] stated that the visual impact of voluminous hair moving in a controlled manner is a universal description of hair with body. Another definition of hair body given by Hough etal. [189] is a measure of a hair mass s resistance to and recovery from externally induced deformation. ... 

The voluminous literature on correlation of ultimate properties with polymer structure cannot be adequately treated here there are many excellent reviews. However, certain aspects of the ultimate properties and their dependence on the time scale of measurement and on temperature are closely allied to viscoelastic properties in small deformations, and these will be briefly discussed. 

The more voluminous reports which theorise a "shape" factor have considered the response of red blood cells however, these cells are readily deformable, subject to osmotic change, and can be conductive, so they are not as easy to study as the rigid "industrial" particulate materials. Gregg and Steidley, Waterman et al., ... 

Asthenosphere The portion of the Earth s mantle below the lithosphere, 10s to 100s of kilometers below the surface, that is actively convecting at rates of centimeters per year and deforming in the solid state. Its temperature is close to the melting point so that it is presumed to be the source region for basalt, the most voluminous product of mantle melting.
