Abstract: This report documents (a.) the results of laboratory tests performed to supplement data previously reported on Reid-Bedford Model (RB) sand and (b.) the results of an analysis of all of the RB laboratory data to develop representative laboratory material properties. The laboratory tests and analysis were conducted for use in evaluating the ability of mathematical constitutive models to simulate the behavior of soils subjected to complex dynamic loadings produced by both explosive- and earthquake-induced ground shock. RB sand is a fine-grained, uniform sand obtained along the Big Black River in Mississippi. The laboratory tests reported consist of consolidated-drained tests and consolidated-undrained tests on saturated sand. The analysis considered the response of the sand under three different test conditions, i.e., unconsolidated-undrained tests on dry sand, consolidated-drained tests on saturated sand, and consolidated-undrained tests on saturated sand. Representative responses of RB sand in terms of uniaxial strain (UX) compressibility; UX stress path; and triaxial compression stress-strain, stress path, and failure are presented for each of the test conditions.
