Investigation of Air Induced Ground Shock Effect Resulting from Various Explosive Sources. Report 2. Influence of Constitutive Models on Ground Motion Predictions

Abstract

The ground shock response in the superseismic range of a one megation air burst on a homogeneous half-space of a soil is considered. Each of the three types of models, was fitted to laboratory test data and calculations were made for each case. Generally, the results from all three models are comparable only when the stress paths in uniaxial strain are comparable for complete load-unload cycles. When this is not so, major differences occur in the lateral motions and stresses.
