Seismic effects of explosions in two-dimensional prestressed models are investigated. This study differs from the conventional two-dimensional modeling in two aspects 1 the medium is prestressed in uniaxial tension and 2 small amounts of chemical explosives are utilized to generate the seismic energy. This energy consists of the combined contributions of the energy in the explosion and the strain energy released from the existing strain field due to cavity formation. Model materials, Plexiglas and aluminum, were chosen on the basis of their widely different elastic properties and physical behavior. Cylindrical charges were detonated and the resulting seismic waves were detected either by capacitance pickups of SR-4 dynamic strain gages. Author
