Preliminary Evaluation of Earth Targets for Use in Impact Effects Studies
Author: Louis Jean Thompson
Publisher:
ISBN:
Category : Artificial satellites
Languages : en
Pages : 70
Book Description
The Aerospace Nuclear Safety Program at Sandia Corporation requires an independent assessment of the safety of all nuclear power supplies used in aerospace under all conditions from factory shipment through re-entry from space. The effects of impact against any point on the earth by a nuclear power supply or its components must be evaluated as part of this assessment. This report: (1) evluates the fundamental mechanisms involved in soil impacts by cylindrical projectiles with velocities of 500-700 feet per second; (2) defines the problem of specifying impact targets which closely simulate various portions of the earth's surface; and (3) describes an analytical and experimental program intended to obtain the information needed to properly specify a simulated earth target for use in Aerospace Nuclear Safety impact tests.

Experimental Studies of Stress-Wave Propagation in Earth Media

Languages : en
Pages : 56
Book Description
The response of several geologic materials to explosively induced spherical shock waves has been studied. Measurements made include stress, particle velocity, and strain gauge time histories at stress levels from 10 to 150 kbars. The influence of water content and cracks was also studied. Gas-gun impact experiments employing oblique target and impactor design have demonstrated the feasibility of studying the propagation of shear waves in plane geometry. (Author).

Earthquakes
Author: W R Matson
Publisher: Morgan & Claypool Publishers
ISBN: 1681743299
Category : Science
Languages : en
Pages : 91
Book Description
This book is an introduction to wave dynamics as they apply to earthquakes, among the scariest, most unpredictable, and deadliest natural phenomena on Earth. Since studying seismic activity is essentially a study of wave dynamics, this text starts with a discussion of types and representations, including wave-generation mechanics, superposition, and spectral analysis. Simple harmonic motion is used to analyze the mechanisms of wave propagation, and driven and damped systems are used to model the decay rates of various modal frequencies in different media. Direct correlation to earthquakes in California, Mexico, and Japan is used to illustrate key issues, and actual data from an event in California is presented and analyzed. Our Earth is a dynamic and changing planet, and seismic activity is the result. Hundreds of waves at different frequencies, modes, and amplitudes travel through a variety of different media, from solid rock to molten metals. Each media responds differently to each mode; consequently the result is an enormously complicated dynamic behavior. Earthquakes should serve well as a complimentary text for an upper-school course covering waves and wave mechanics, including sound and acoustics and basic geology. The mathematical requirement includes trigonometry and series summations, which should be accessible to most upper-school and college students. Animation, sound files, and videos help illustrate major topics.
