Available in PDF, EPUB and Kindle. Book excerpt: In an effort to better understand the nature and the limitations of impact testing, the Charpy impact test was studied in detail via instrumentation of both the tester and the specimen. It was found that the energy associated with the impact testing of cemented carbide consists mainly of elastic bending energy and absorption of energy by the testing machine. The vibrational and plastic components are insignificant. The toss energy and energy necessary to create new surfaces can be fairly well calculated from other considerations. The tests have shown no rate effects in cemented carbides, and the state of stress in the beam is uniaxial tension. Thus the test does not describe the material's propensity for cleavage or brittle failure, but rather describes mainly the modulus and strength of cemented carbides (which are routinely and more easily measured in other ways), and the stiffness of the testing machine--all of which have very little bearing on the toughness of the cemented carbide. The components which describe this are the energy of plastic work and the energy necessary to create two new surfaces, and these consist of only a few percent of the total measured energy. The amount of energy which the machine absorbs will vary with the modulus and strength of the material being tested. In the case of a hard low-strength grade like Carboloy Grade 320, the anvil sees very little load before failure and thus the energy partitioning will be significantly different than that for a stronger grade.

Available in PDF, EPUB and Kindle. Book excerpt: The impact energy or impact strength of WC-Co alloys is currently determined by loading an unnotched 1/4 inch x 1/4 inch x 2 inch sample in three point bending. This is done on a Charpy Impact tester of 24 ft. lbs. capacity (Model CIM-24, Manlabs, Inc.). The results of these tests are generally considered to be an indication of the 'toughness' of cemented carbide. However, much of the field experience where carbide is subjected to impact loading, such as in mining, does not correlate well with the charpy impact values of the various grades of cemented carbides. In an effort to better understand the nature and the limitations of impact testing, the above mentioned test was studied in detail via instrumentation of both the tester and the specimen.

Available in PDF, EPUB and Kindle. Book excerpt: The International Conference on Fracture of Concrete and Rock was organized by the Society for Experimental Mechanics (SEM) subdivision on Fracture of Concrete and Rock and RILEM Committee 89-FMT Fracture MechanicS of Concrete; Test Methods. The venue was Houston, Texas on June 17-19, 1987 and cooperation was provided by ACI 446, Fracture Mechanics and RILEM 90-FHA Fracture Mechanics of Concrete; Applications. The conference co-chai rmen were Professor S. P. Shah, Northwestern Uni versity and Professor S. E. Swartz, Kansas State University with the able assistance of Professor K. P. Chong, University of Wyoming. The conference theme was Fracture Mechanics Applications to Cracking and Fracture of Concrete (plain or reinforced) and Rock Subjected to Uniaxial or Complex Stress States with Static- or Dynamic-Loading Rates. This theme was chosen in recognition of parallel efforts between the rock mechanics community and researchers working in the application of fracture mechanics methods to the problem of cracking and fracture of concrete.

Book Synopsis From Charpy to Present Impact Testing by : D. Francois
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.

Available in PDF, EPUB and Kindle. Book excerpt: These volumes constitute the Proceedings of a Symposium ort the Fracture Mechanics of Cerarnics, held at the Pennsylvania State University, University Park, Pennsylvania, July 11, 12, and 13, 1973. The theme of the symposium focussed on the mechanical behavior of brittle cerarnics in terms of the characteristics of cracks. The 52 contributed papers by 87 authors, present an overview of the cur rent understanding of the theory and application of fracture mechan ics to brittle cerarnics. The prograrn chairmen gratefully acknowledge the financial assistance for the Symposium provided by the Office of Naval Re search, the College of Earth and Mineral Sciences of the Pennsyl vania State University, the Materials Research Center of Lehigh University, Bethlehem, Pennsylvana and Westinghouse Research Laboratories, Pittsburgh, Pennsylvania. Special appreciation is extended to the expert organization provided by the J. Orvis Keller Conference Center of the Pennsyl vania State Conference Center of the Pennsylvania State University. In particular, Mrs. Patricia Ewing should be acknowledged for the excellent prograrn organization and planning. Dean Harold J. O'Brien, who was featured as the after-dinner speaker and who presented a most stimulating talk on the cornrnunication between people, also contrib uted to the success of the meeting. Finally, we also wish to thank our joint secretaries for the patience and help in bringing these Proceedings to press. University Park R. C. Bradt Bethlehem D. P. H.
