Download or read book Hypervelocity Impact Analysis by the Method of Characteristics written by Richard Madden and published by . This book was released on 1969 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: A computer method has been developed for the analysis of the initial hydrodynamic phase of hypervelocity impact. The method is based on solving the inviscid, non heat-conducting, unsteady fluid dynamic equations in cylindrical coordinates by utilizing an approach based on the method of characteristics. The method has been used to generate an operational computer program applicable to the impact of an infinitely long right circular cylinder striking a semi-infinite target of the same material. The projectile is assumed to be traveling parallel to its axis of symmetry, and the target is initially at rest. Results are presented for the pressure and velocity fields at various times following the impact. The pressure fields are compared with the pressure fields calculated from an existing hydrodynamic analysis.
