A combined theoretical and model study of the basic physics of wave propagation, as applied to problems in mechanical radiation in the real earth, was conducted. During the support period covered by the report the effort was directed along three primary lines a improvement and augmentation of the model laboratory, b the development of seismic model sources capable of delivering mechanical pulses with broad frequency spectra, and c an investigation of the dynamic rheological properties of a model material to be used in the study of wave propagation in an elastic materials.
