ABSTRACT
A split Hopkinson pressure bar (SHPB) was used to measure the mechanical behavior of Navy explosive PBXC-129 (a high-solids-loaded explosive material) with strain rates up to ~3500 s[SUP-1]. The PBXC-129's high-strain response is typical of other explosive and propellant behavior. At higher strain rates, the PBXC-129 shows significant stiffening with a possible reaction. Stress-strain curves and material properties for PBXC-129 are presented in this paper.

    Unsteady compressive waves were measured in the plastic-bonded, HMX-based explosive PBX 9501 using multiple, embedded, magnetic gauges that measured particle velocity. Records were obtained for impact stresses near 300 and 570 MPa. These results are analyzed using Lagrangian analysis to obtain...

    The split Hopkinson pressure bar technique has been used successfully to characterize high strain-rate behavior (10[sup 3] to 10[sup 4] s[sup -1] ) of metals and polymeric materials in the past. Similar studies on composite energetic materials are desired to assist in developing a model that...

    The existing constitutive models of concrete elasto-plasticity are generally based on an assumed initial yield surface and on the unrealistic uniaxial stress-strain curves. In this paper, a new expression for the loading surface has been proposed and the model has been calibrated by using well...

The procedure is based on the assumption of an internal core of intact material always present inside a specimen in uniaxial-compression. This involves a modification...
