Nonlinear Response of Buried Structures in a Stress Wave Environment.

Abstract

The theoretical behavior of three buried structural configurations in a stress wave environment has been determined using finite element techniques. The three structures considered are an unlined cylindrical cavity and two thick-walled composite cylinders. Both composite structures are steel lined and each has a thick concrete outer layer; one being cellular concrete and the other reinforced concrete. The impinging wave simulates an underground explosion and its strength was such that nonlinear behavior occurred in the soil-like surrounding medium (NTS tuff) as well as the composite structures.
