Abstract:

This report describes a calculation program designed to predict the cratering dimensions and free-field ground motions which result when chemical or nuclear detonations occur with various degrees of confinement. Calculations were made using a two-dimensional plastic-elastic time dependent code. A vital part of the program involved the derivation of calculational models capable of describing the response of earth media to shock loading. Author
