2011 APR 27 - (VerticalNews.com) -- "Snow is an agglomerate of ice crystals. Therndetails of its mechanical behavior are still controversially discussed: what is the relativernimportance of intragranular-viscoplastic deformation versus grain boundary sliding underrnmechanical loading? In order to understand how snow deforms at the grain scale, micromechanicalrncompression tests on dry snow have been performed using X-ray diffraction contrastrntomography (DCT)," scientists writing in the journal Advanced Engineering Materials report.
