Book Description
This report compares seven double-plate penetration predictor equations for accuracy and effectiveness of a shield design. Three of the seven are the Johnson Space Center original, modified, and new Cour-Palais equations. The other four are the Nysmith, Lundeberg-Stern-Bristow, Burch, and Wilkinson equations. These equations, except the Wilkinson equation, were derived from test results, with the velocities ranging up to 8 km/sec. Spreadsheet software calculated the projectile diameters for various velocities for the different equations. The results were plotted on projectile diameter versus velocity graphs for the expected orbital debris impact velocities ranging from 2 to 15 km/sec. The new Cour-Palais double-plate penetration equation was compared to the modified Cour-Palais single-plate penetration equation. Then the predictions from each of the seven double-plate penetration equations were compared to each other for a chosen shield design. Finally, these results from the equations were compared with test results performed at the NASA Marshall Space Flight Center. Because the different equations predict a wide range of projectile diameters at any given velocity, it is very difficult to choose the "right" prediction equation for shield configurations other than those exactly used in the equations' development. Although developed for various materials, the penetration equations alone cannot be relied upon to accurately predict the effectiveness of a shield without using hypervelocity impact tests to verify the design.Hayashida, K.

Book Description
Covering the broad spectrum of modern structural engineering topics, the Handbook of Structural Engineering is a complete, single-volume reference. It includes the theoretical, practical, and computing aspects of the field, providing practicing engineers, consultants, students, and other interested individuals with a reliable, easy-to-use source of information. Divided into three sections, the handbook covers:

Book Description
This book contains the proceedings of EXPLOMETTM 2000, International Conference on Fundamental Issues and Applications of Shock-Wave and High-Strain-Rate Phenomena, held in Albuquerque, New Mexico, 2000; the fifth in the EXPLOMETTM quinquennial series which began in Albuquerque in 1980. The book is divided into five major sections with a total of 85 chapters. Section I deals with materials issues in shock and high strain rates while Section II covers shock consolidation, reactions, and synthesis. Materials aspects of ballistic and hypervelocity impact are covered in Section III followed by modeling and simulation in Section IV and a range of novel applications of shock and high-strain-rate phenomena in Section V. Like previous conference volumes published in 1980, 1985, and 1995, the current volume includes contributions from fourteen countries outside the United States. As a consequence, it is hoped that this book will serve as a global summary of current issues involving shock and high-strain-rate phenomena as well as a general reference and teaching componant for specializd curricula dealing with these features in a contemporary way. Over the past twenty years, the EXPLOMETTM Conferences have created a family of participants who not only converse every five years but who have developed long-standing interactions and professional relationships which continue to stimulate new concepts and applications particularly rooted in basic materials behavior.
