Available in PDF, EPUB and Kindle. Book excerpt: The report is the third in a series, 'Ground Shock Calculation Parameter Study, ' centered on the Prairie Flat Event. The first report describes the effect of different elastic-ideally plastic constitutive model formulations on calculated ground shock, while the second report describes the effect of different bottom boundary conditions. The report documents the results of a parameter study conducted to determine the effects of using different types of nonlinear constitutive models to fit a given set of soil property data in calculations of high-explosive, airblast-induced, superseismic ground shock.

Book excerpt: A parametric study was conducted to determine the effect of using various nonlinear elastic-plastic constitutive model formulations to fit a given set of soil property data in calculating high-explosive (HE), airblast-induced, superseismic ground shock. The code used was a modified version of the 2D axisymmetric LAYER code developed by the Paul Weidlinger firm. A constant shear modulus model, a constant Poisson's ratio model, and a hybrid-type model were employed. Two series of calculations were performed. In the first, the effect of an HE-type airblast on a deep highly compressible layer of soil was investigated for the three different models. In the second series, a two-layer soil profile comprising a shallow layer of highly compressible soil over a deep highly incompressible material was used. The study showed that the radial stress-, velocity-, and displacement-time histories at shallow depths were strongly influenced by the type of constitutive model used to represent the soils' mechanical behavior. Relatively large differences in maximum and final radial displacement were observed for the different models. (Author).

This book was released on 1973 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Outrunning ground shock data from the 100- to 10-psi overpressure decade in six large surface high explosive (HE) tests, three from a rock site and three from a glaciated soil site, were analyzed for the effect of gross changes in constitutive properties. Axisymmetric wave propagation code calculations in layered linear and nonlinear (incrementally elastic-plastic) media were performed to determine the effects of introducing nonlinearity, selected material property variations, and the relative importance of airblast and direct induced effects from surface explosions in the overpressure decade of interest.
