TRAJECTORY ANALYSIS FOR STRUCTURAL FRAGMENTS.
Abstract
Trajectories of structural fragments subject to nuclear blast winds are analyzed on the following basis: Total trajectory time is considered to be freefall time of drop from initial fragment height; Drag in vertical direction is neglected; Blast winds are considered effective for total trajectory time, i. e., structural failure occurs at time of shock arrival and does not affect the shape of the free-field blast wave; Negative phase winds are included in the analysis; Trajectories are computed for spherical masonry fragments, yielding results for certain values of effective aerodynamic coefficients; and Effects of orientation and rotation on the effective aerodynamic coefficients for angularly-shaped objects are not included.
