Enhanced Diffusion in Shock Activated Be-Al Interfaces
نویسندگان
چکیده
Enhanced diffusion of aluminum in shock activated beryllium has been observed. Cylindrical samples of aluminum coated beryllium rods were axisymetrically loaded up to 40 Gpa and a total residual strain of up to 6.74. The defect microstructure produced by both the shock wave and strain enabled the transport of aluminum in beryll~um to exceed its equilibrium solid state saturation. This "super saturated" aluminum. upon heating exsolves out at relatively low temperatures and forms very strong interfaces with pressure mated components.

A Modified Flux Vector Splitting Scheme for Flow Analysis in Shock Wave Laminar Boundary Layer Interactions
The present work introduces a modified scheme for the solution of compressible 2-D full Navier-Stokes equations, using Flux Vector Splitting method. As a result of this modification, numerical diffusion is reduced. The computer code which is developed based on this algorithm can be used easily and accurately to analyze complex flow fields with discontinuity in properties, in cases such as shock...

Introduction:This study examined the effects of administration of subcutaneous β-estradiol on PTSD-like symptoms (the enhanced conditioned fear response, CFR) that induced by a single-prolonged stress (SPS) and shock in rats. Adult male Wistar rats were exposed to SPS procedure: restraint for 2 h, forced swim for 20 min, and ether anesthesia. Then the rats were placed in fear conditioning syste...
