Book Synopsis Dynamic Fracture Analysis of Notched Bend Specimens by : S. Mall
Download or read book Dynamic Fracture Analysis of Notched Bend Specimens written by S. Mall and published by . This book was released on 1980 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dynamic finite-element code was used to determine dynamic initiation fracture toughness, KId, in 25.4-mm-thick (1 in.) notched bend specimens of A533B steel and a 15.9-mm-thick (5/8 in.) dynamic tear specimen of 6061 aluminum alloy. These specimen types can reflect varying dynamic fracture response due to differences in test temperature, specimen geometry, and material as well as notch tip sharpness. Measured load-time histories were applied to the tup as modeled by finite elements, and the dynamic stress-intensity factor was computed by a calibrated crack opening displacement procedure. Dynamic stress-intensity factors were also computed by the ASTM Test for Plane-Strain Fracture Toughness of Metallic Materials (E 399-74) using a load based on local dynamic strain measurements and a static K calibration.

Available in PDF, EPUB and Kindle. Book excerpt: A dynamic finite element code was used to determine dynamic initiation fracture toughness, K sub Id. in 25.4 mm (1 in.) thick notched bend specimens of A533 B steel and a 15.9 mm (5/8 in.) thick dynamic tear (DT) specimen of 6061 aluminum alloy. These specimen types can reflect varying dynamic fracture response due to differences in test temperature, specimen geometry and material as well as notch tip sharpness. Measured load-time histories were applied to the tup as modeled by finite elements and the dynamic stress intensity factor was computed by a calibrated COD procedure. Dynamic stress intensity factors were also computed by the ASTM E-399 procedure using a load based on local dynamic strain measurements and a static K-calibration. Reasonable agreements between measured and computed dynamic strains in the vicinity of the crack tip verified the accuracy of the dynamic finite element model. The attendant agreement between measured versus computed time-varying dynamic stress intensity factors also verified, for the first time, the applicability of the ASTM E-399 procedure for computing dynamic initiation fracture toughness, K sub Id on the basis of local dynamic strain measurements.

Book Synopsis Impacted Notch Bend Specimen by : A. S. Kobayashi
Download or read book Impacted Notch Bend Specimen written by A. S. Kobayashi and published by . This book was released on 1981 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed method for testing and evaluating data generated by instrumented impact testings of notch bend specimens is evaluated by the experimental and numerical dynamic fracture results obtained in the past. As expected, brittle fracture of the photoelastic, steel and aluminum impacted notch specimens considered in this paper cannot be predicted by the static stress intensity factors at the instant of crack propagation. The fracture energy was only a fraction of the total absorbed energy and was equally unsuitable for dynamic fracture characterization of these specimens. This critical evaluation of the proposed method suggests that despite the enormous correlation studies which justify the use of static analysis, neither the proposed method nor the resultant static stress intensity factor should be used to evaluate the fracture data of impacted notch bend specimens of slightly different configurations.

Book Synopsis Dynamic Fracture by : K. Ravi-Chandar
Download or read book Dynamic Fracture written by K. Ravi-Chandar and published by Elsevier. This book was released on 2004-10-16 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic fracture in solids has attracted much attention for over a century from engineers as well as physicists due both to its technological interest and to inherent scientific curiosity. Rapidly applied loads are encountered in a number of technical applications. In some cases such loads might be applied deliberately, as for example in problems of blasting, mining, and comminution or fragmentation; in other cases, such dynamic loads might arise from accidental conditions. Regardless of the origin of the rapid loading, it is necessary to understand the mechanisms and mechanics of fracture under dynamic loading conditions in order to design suitable procedures for assessing the susceptibility to fracture. Quite apart from its repercussions in the area of structural integrity, fundamental scientific curiosity has continued to play a large role in engendering interest in dynamic fracture problems In-depth coverage of the mechanics, experimental methods, practical applications Summary of material response of different materials Discussion of unresolved issues in dynamic fracture

It also includes the study of engineering countermeasures to dynamic instability of rock and rock masses. The topics in the book include: - Dynamic theories - Numerical simulation - Propagation of stress waves - Dynamic tests of rock - Stability of underground openings under dynamic loading - Rockburst - Seismic monitoring - Dynamic rock support - Blasting - Earthquake-related rock structure damage, etc. Applications, such as rockburst, dynamic rock support, seismic monitoring, blasting and earthquake-related rock structure damage, are paid special attention in Rock Dynamics – Experiments, Theories and Applications. The papers, from specialists both from mining and tunnelling branches, discuss commonly interested dynamic issues. Their experience and knowledge in the application of rock dynamics are extremely valuable for all academics, engineers and professionals who work with rock dynamics.
