    Effect of Pressure and Shock Wave Risetime on Material Ejection

    A two-dimensional elastic and plastic hydrodynamics code MEPH is applied to simulate ejecting process. We focus on the effect of shock pressure and shock risetime on mass ejection from shocked aluminum. It shows that with increase of shock pressure the ejecting factor keeps increasing, but the ejecting factor is not sensitive to the shock pressure. The effect of shock risetime on the mass ejection from shocked aluminum is also investigated. Numerical results agree well with experiments. The mass ejection is sensitive to shock risetime.

    Shock Mitigation Studies of Solid Foams for Z-Pinch Chamber Protection
    21st IEEE/NPS Symposium on Fusion Engineering SOFE 05 (2005)

    Solid open-cell Al foams are subjected to dynamic compression testing in a vertical shock tube to model the metallic foam being considered for use in an inertial fusion energy reactor. High porosity (0.89) foam samples (stack of two, 25.4 cm square, 10.2 cm high) of three different cell sizes (10, 20, and 40 pores per inch) are compressed with a strong shock (M=6) in a 25 kPa atmosphere of air and SF 6 . The post-shock samples are highly compressed (strains up to 0.8 for the smallest cell size) and have a wavy upper surface indicating structural anisotropy. Energy absorption is found to vary with cell-size (smaller cells, more absorption) while the impulse of the shock wave is independent of cell size. Pressure data indicate the incident shock wave becomes a compression wave with a non-discontinuous gradient inside of the foam. Using an array of pressure transducers with a vertical spacing of 2.54 cm, the wave speed in the foam sample is reduced to 25% of its value without the presence of the foam

    Thermal Shock Testing
    Journal of the American Ceramic Society (1955)
    W. R. Buessem
    Practical experience has shown that thermal shock tests do not lead to generally useful test data. This is probably due to the fact that thermal shock failure is a complicated function of the external thermal shock conditions and of the temperature functions of five different material properties. These five material functions appear in a different combination in almost every thermal shock case and cannot be extracted from thermal shock test data. It is recommended that these five properties and their temperature dependence be determined by separate standard tests, not employing thermal shock. If the five property functions are known, thermal shock tests proper can be used to determine the maximum thermal shock stresses in any device.

    Detonation Initiation via Imploding Shock Waves
    36th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit (2004)
    Scott I. JacksonJ. E. Shepherd
    An imploding annular shock wave driven by a jet of air was used to initiate detonations inside a 76 mm diameter tube.The tube was filled with a test gas composed of either stoichiometric ethylene-oxygen or propane-oxygen diluted with nitrogen.The strength of the imploding shock wave and the sensitivity of the test gas were varied in an e↵ort to find the minimum shock strength required for detonation of each test mixture.The results show that the minimum required shock strength increases with mixture sensitivity and suggest that impractically large shock driver pressures are required to initiate detonations in ethylene-air or propane-air mixtures when using this technique.Nomenclature t 23 Duration between wave arrival at ST2 and ST3 x 23 Distance between ST2 and ST3 M 23 Average Mach number between ST2 and ST3 P Pressure R Gas constant T Temperature u Velocity, lab frame w Velocity, shock-fixed frame
