Elastic Constants of Artificial and Natural Ice Samples by Brillouin Spectroscopy
Abstract The method of Brillouin spectroscopy has been used to measure the dynamic elastic moduli of local homogeneous regions in ice samples representing four different environments of formation. These included artificial ice frozen from distilled water, clear monocrystalline glacial ice, bubbly la...
