The detection of structural transformations in kaolin suspensions by ultrasound (1999)
Journal Article
Austin, J. C., & Challis, R. E. (1999). The detection of structural transformations in kaolin suspensions by ultrasound. Journal of Colloid and Interface Science, 220(1), 6-12. https://doi.org/10.1006/jcis.1999.6488

Thefractal dimension of kaolin flocs suspended in water was increased by the addition of potassium chloride and indirectly monitored by low-power ultrasonic pulses in a test cell with a “pitch-catch” configuration. The results from these measurements... Read More about The detection of structural transformations in kaolin suspensions by ultrasound.

Ultrasonic propagation through aqueous kaolin suspensions during degassing (1999)
Journal Article
Austin, J. C., & Challis, R. E. (1999). Ultrasonic propagation through aqueous kaolin suspensions during degassing. Ultrasonics, 37(4), https://doi.org/10.1016/S0041-624X%2899%2900004-9

A degassing procedure is necessary prior to taking ultrasonic measurements in aqueous kaolin suspensions as well as many other liquid based colloids. In this work we compare two degassing methods and show that subjecting a sample to a power ultrasoun... Read More about Ultrasonic propagation through aqueous kaolin suspensions during degassing.

Buckling of an elastic half-space with surface imperfections (1999)
Book Chapter
(1999). Buckling of an elastic half-space with surface imperfections. In 1st Canadian Conference on Nonlinear Solid Mechanics: CanCNSM, Victoria, British Columbia, Canada, June 16-June 20, 1999 (99 -107)

Over the years, linear analysis of the stability of pre-stressed elastic half-spaces has been carried out for various kinds of materials and various forms of pre-stress; see Biot (1965), Nowinski (1969a, b), Willson (1973a, b), Usmani \& Beatty (1974...
