| Abstract: | Abstract: 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. |
