Three-Dimensional Hydrodynamic Code Study.

Abstract

A study of zone changes (thickness) indicated very small changes in peak pressure. A 2D calculation was performed for a coupling experiment. Quadrilateral zones rather than rectangular zones are required to accurately model curved surfaces. If the total impulse is the important factor to be calculated for structures, existing numerical codes and computers may be adequate to give trends, rather than absolute values. (Author)
