| abstracts | Glass granules and grains of crushed glass usually replace sand if photo-elastic observation of
load-transmitting ‘force chains’ is planned. Still an open question exists however, how well glass granules
can represent real sand grains. This paper in its first part compares simple uniaxial crushing tests on glass
grains (both granules and crushed glass) and on coarse sand grains (micro-scale). Some basic geometrical
characteristics of glass and sand grains are discussed, then the measurement techniques are presented and
the results of crushing tests demonstrated. The second part of the paper contains the results of ‘macro-scale’
loading tests on big granular samples, made of ~106 glass or sand grains. The deformation characteristics of
these samples differ significantly. |
