Shear strengths of aluminium nitride and titanium diboride under plane shock wave compression
This work compares the estimates of shear strengths of aluminium nitride and titanium diboride obtained (a) from the simultaneous measurements of longitudinal and lateral stress by means of manganin gauges under plane shock wave loading with (b) those calculated from the offset between hydrodynamic and shock Hugoniot of these materials. The results of this work show that whereas the estimates o...
متن کاملDynamic Enhancement and Multi-axial Behavior of Honeycombs under Combined Shear- Compression Doctoral Committee
III Abstract: This study aims at the energy absorption problems in the crash of high speed vehicles, bird impact and crashworthiness design of aircraft, and the dynamic enhancement and multi-axial behavior of honeycombs under combined shearcompression are investigated. The study consists mainly of two parts. The first part is related to the dynamic strength enhancement of honeycombs under uniax...
متن کاملNumerical Simulation of Shock-Wave/Boundary/Layer Interactions in a Hypersonic Compression Corner Flow
Numerical results are presented for the shock-boundary layer interactions in a hypersonic flow over a sharp leading edge compression corner. In this study, a second- order Godunov type scheme based on solving a Generalized Riemann Problem (GRP) at each cell interface is used to solve thin shear layer approximation of laminar Navier-Stokes (N-S) equations. The calculated flow-field shows general...
متن کاملShock wave compression of ironsilicate garnet
Shock wave Hugoniot data have been obtained for almandine-garnet of composition (Fe•.7•, Mgo.14, Ca•.•, Mno.•) Al,iaO• to pressures of >650 kb. The Hugoniot data indicate the onset of a high-pressure phase at 195 ñ 20 kb. Equation-of-state systematics and crystal chemical data (stemming largely from analog compounds) suggest that the high-pressure phase occurs in an 'ilmenitelike' structure wit...
متن کاملShock wave compression of singlecrystal forsterite
Hugoniot equation of state measurements have been performed on pure synthetic single-crystal forsterite (Mg•SiO4) in the pressure range 70-160 GPa (0.7-1.6 Mbar). These and earlier data for polycrystalline forsterite are compared with theoretical Hugoniots for the assemblages 2MgO (rocksalt) + SiO: (stishovite) and MgO (rocksalt) + MgSiO8 (perovskite). The densities attained by single-crystal f...
