Download or read book Investigation of the High Speed Impact Behavior of Fibrous Materials written by Robert J. Coskren and published by . This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A group of Nomex and glass webbings were evaluated for impact tensile behavior at testing speeds of 200 to 700 feet per second. It was found that the impact energy absorption of Nomex webbings decreases with increasing testing speed until at 700 feet per second there may be experienced a loss as much as 88 percent of the static value. Elevated temperature exposure of Nomex webbing in a freely relaxed condition prior to impact testing appears to be helpful in improving performance at both 500 and 700 feet per second, but is of little importance at 200 feet per second. Glass webbings, while poorer on a weight basis than Nomex, showed improvements in energy absorption capability with increased testing speed, one spliced sample indicating almost a tenfold increase over its static energy value.

Download or read book Developments in Modern Racecar Driver Crash Protection and Safety written by John Melvin and published by SAE International. This book was released on 2013-10-14 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, the evolution of safety improvements in motorsports was the result of a combination of science and perceived safe practices. Most safety developments were not based on rigorous laboratory testing, but rather on intuition and a “let’s try it and see what happens” approach. During the last few decades, motorsports has benefited from the organized research efforts made possible by academia, manufacturers, and sanctioning bodies, leading to present-day motorsports safety methodologies based on solid data and testing. This compendium, edited by some of the foremost racing safety experts, comprises selected technical papers that document the development and implementation of key motorsports safety technologies now in use. It is intended to provide racing professionals and enthusiasts with a concise overview of the significant engineering developments in motorsports driver safety that has occurred during the past two decades. The 13 papers chosen for this compendium, published between 1990 and 2013, reflect landmark safety studies and developments of that time. Eleven of the papers were published by SAE International and two were presented at the Stapp Car Crash Conference. The papers cover the following topics: • Crash testing simulations • Human crash injury and survival • Reducing driver injury in severe crashes • Head and neck restraints, including the HANS device • Race car seats • Restraint systems • Track safety and barrier systems The final paper is a study on the detailed performance of restraint systems and seats in examples of severe stock car crashes. The paper represents a succinct example of modern crash investigation of racing crashes with crash recording data, detailed injury analysis, and protective system performance. The progress in motorsports safety, as described in this compendium, has been dramatically effective in reducing driver injuries at the top levels of motorsports. Unfortunately, this is not true at the lower levels, where drivers continue to suffer preventable injuries and fatalities.

Download or read book From Charpy to Present Impact Testing written by D. Francois and published by Elsevier. This book was released on 2002-06-18 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: From Charpy to Present Impact Testing contains 52 peer-reviewed papers selected from those presented at the Charpy Centenary Conference held in Poitiers, France, 2-5 October 2001. The name of Charpy remains associated with impact testing on notched specimens. At a time when many steam engines exploded, engineers were preoccupied with studying the resistance of steels to impact loading. The Charpy test has provided invaluable indications on the impact properties of materials. It revealed the brittle ductile transition of ferritic steels. The Charpy test is able to provide more quantitative results by instrumenting the striker, which allows the evolution of the applied load during the impact to be determined. The Charpy test is of great importance to evaluate the embrittlement of steels by irradiation in nuclear reactors. Progress in computer programming has allowed for a computer model of the test to be developed; a difficult task in view of its dynamic, three dimensional, adiabatic nature. Together with precise observations of the processes of fracture, this opens the possibility of transferring quantitatively the results of Charpy tests to real components. This test has also been extended to materials other than steels, and is also frequently used to test polymeric materials. Thus the Charpy test is a tool of great importance and is still at the root of a number of investigations; this is the reason why it was felt that the centenary of the Charpy test had to be celebrated. The Société Française de Métallurgie et de Matériaux decided to organise an international conference which was put under the auspices of the European Society for the Integrity of Structures (ESIS). This Charpy Centenary Conference (CCC 2001) was held in Poitiers, at Futuroscope in October 2001. More than 150 participants from 17 countries took part in the discussions and about one hundred presentations were given. An exhibition of equipment showed, not only present day testing machines, but also one of the first Charpy pendulums, brought all the way from Imperial College in London. From Charpy to Present Impact Testing puts together a number of significant contributions. They are classified into 6 headings: •Keynote lectures,•Micromechanisms,•Polymers,•Testing procedures,•Applications,•Modelling.
