A NONLINEAR FINITE ELEMENT CODE FOR ANALYZING THE BLAST RESPONSE OF UNDERGROUND STRUCTURES.

Abstract

A nonlinear, axisymmetric, dynamic finite-element method of analysis computer program is developed. Elastic, two-dimensional problems can also be analyzed without loss of efficiency. A FORTRAN IV listing of the computer code is presented along with information on utilizing the code to run problems. Analytical results are compared with experimental data obtained from testing a modeled buried structure subjected to a blast loading. (Author)
