Dilatancy (granular material) / internal erosion. The use of appropriate filters is critical to managing these materials; I like a #4 sized clear gravel / coarse-grained sand as a commercial aggregate which is generally readily available. Some non- woven filter fabrics are also suitable. As with all filters, D15 and D50 compatibility criteria should be checked. Dilatancy (granular material) Dilatancy is the volume change observed in granular materials when they are subjected to shear deformations. This effect was first described scientifically by Osborne Reynolds in 1885/1886 and is also known as Reynolds dilatancy. Unlike most other solid materials, the tendency of a compacted
Granular synthesis possible. Greek composer Iannis Xenakis is known as the inventor of the granular synthesis technique. Canadian composer Barry Truax was one of the first to implement real-time versions of this synthesis technique. "Granular synthesis has been implemented in different ways, notably by the Canadian composer Barry Truax." There are now many dedicated devices available for exploring granular synthesis without using a computer. Many of these devices are in the Eurorack modular synthesizer format, such as: Granular synthesis Granular synthesis is a basic sound synthesis method that operates on the microsound time scale. It is based on the same principle as
