PROCEDURES FOR PREDICTION OF GROUND SHOCK PHENOMENA BASED ON ONE-DIMENSIONAL SHOCK PROPAGATION CONSIDERATIONS. REPORT 1. PROCEDURES AND APPLICATIONS
The report demonstrates procedures for computing stress and motion histories in soil. Simplified geometries are employed. The procedures have application to analysis of nuclear weapon loadings. The methods are based on the conservation laws of mass and momentum and dynamic material properties in the...
