Available in PDF, EPUB and Kindle. Book excerpt: Use has been made of cavities, machined in a typical hypervelocity impact target material, to evaluate methods used to measure volumes, depths, and diameters of impact craters. Depth and diameter measurement techniques in use have been found to produce errors, typically, of 0.1 and 0.5%, respectively. The liquid metering method of volume measurement has been found to produce large errors (7 to 44%) when applied in conjunction with the saturation wetting which is common. Wall coating and selective adjustment of wetting properties of the filling agent have been shown to provide effective means for minimizing meniscus errors; errors smaller than two percent result in cases where diameter is 0.5 in. or more and total volume exceeds 0.06 cc. The latter technique is inapplicable to accurate measurement of the volumes of small craters (diameters of 0.3 in. or less) wherein capilarity predominates; machining away of crater lips and metering level full produces more satisfactory results.

Book excerpt: Craters in copper and lead, produced by hypervelocity impact, have been measured and the dimensions correlated with impact velocity. The results indicate that craters scale with about the 1.7 power of velocity, in agreement with computer physics results based upon hydrodynamic calculations.

Book Synopsis High-Velocity Impact Phenomena by : Ray Kinslow
Download or read book High-Velocity Impact Phenomena written by Ray Kinslow and published by Elsevier. This book was released on 2012-12-02 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: High-Velocity Impact Phenomena covers a wide range of pertinent topics dealing with impact phenomena. The book discusses hypervelocity accelerators; stress wave propagation in solids; and the theory of impact. The text also describes the application of the theory of impact on thin targets and shields and correlation with experiment; the numerical evaluation of hypervelocity impact phenomena; and analytical studies of impact-generated shock propagation. The equation of state of solids from shock wave studies; metallurgical observations and energy partitioning; and engineering considerations in hypervelocity impact are also encompassed. Design engineers will find the book invaluable.

Download or read book Survey of Hypervelocity Impact Information written by Walter Herrmann and published by . This book was released on 1961 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the survey of high velocity impact information, a great deal of data was accumulated. Considerable difficulty was experienced in extracting original measured quantities, and originating laboratories were contacted whenever possible to supply tabulated data and additional information concerning material properties and measuring techniques. In some cases, such information was no longer available, and information was extracted from graphical data plots, and material properties corresponding to the material specifications were extracted from handbooks. The collected data are organized and presented under separate headings according to the projectiletarget configuration. (Author).

Book Synopsis Two-dimensional Computer Simulation of Hypervelocity Impact Cratering by :
Download or read book Two-dimensional Computer Simulation of Hypervelocity Impact Cratering written by and published by . This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A computational approach used for subsurface explosion cratering has been extended to hypervelocity impact cratering. Meteor (Barringer) Crater, Arizona, was selected for our first computer simulation because it was the most thoroughly studied. It is also an excellent example of a simple, bowl-shaped crater and is one of the youngest terrestrial impact craters. Shoemaker estimates that the impact occurred about 20,000 to 30,000 years ago (Roddy (1977)). Initial conditions for this calculation included a meteorite impact velocity of 15 km/s. meteorite mass of 1.57E + 08 kg, with a corresponding kinetic energy of 1.88E + 16 J (4.5 megatons). A two-dimensional Eulerian finite difference code called SOIL was used for this simulation of a cylindrical iron projectile impacting at normal incidence into a limestone target. For this initial calculation a Tillotson equation-of-state description for iron and limestone was used with no shear strength. A color movie based on this calculation was produced using computer-generated graphics. Results obtained for this preliminary calculation of the formation of Meteor Crater, Arizona, are in good agreement with Meteor Crater Measurements.
