High-Velocity Impact Phenomena


Book Description

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.







Hypervelocity Impact Phenomena


Book Description

The parameters governing the failure of thin metal plates under the impact of high-speed fragments are being studied; special emphasis is placed on the lightweight structural alloys. The geometrical features of the perforations, together with the spatial, mass, and velocity distributions of the ejecta produced in the perforation process, are considered. A few select target materials e.g., Al and Pb are currently being investigated under impact conditions that involve the same projectile geometry but different impact velocities. (Author).










High-Pressure Shock Compression of Solids VIII


Book Description

Research in the field of shock physics and ballistic impact has always been intimately tied to progress in development of facilities for accelerating projectiles to high velocity and instrumentation for recording impact phenomena. The chapters of this book, written by leading US and European experts, cover a broad range of topics and address researchers concerned with questions of material behaviour under impulsive loading and the equations of state of matter, as well as the design of suitable instrumentation such as gas guns and high-speed diagnostics. Applications include high-speed impact dynamics, the inner composition of planets, syntheses of new materials and materials processing. Among the more technologically oriented applications treated is the testing of the flight characteristics of aeroballistic models and the assessment of impacts in the aerospace industry.




A Second Order Numerical Model for High Velocity Impact Phenomena


Book Description

A second order accurate code for penetration problems associated with high velocity impact of materials that exhibit elastic or elastic plastic behavior has been developed. The model uses a finite difference method based upon an Eulerian formulation of the basic differential equations. For interior mesh points, the difference equations are second order accurate. The boundary is explicity preserved as a discontinuity by the use of tracer particles whose positions mark the current interface or free surface position. On such curves free surface and interface boundary conditions are applied. An example of a penetration interaction problem is presented.
