Download or read book Split Hopkinson Kolsky Bar written by Weinong W. Chen and published by Springer Science & Business Media. This book was released on 2010-11-11 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors systematically describe the general principles of Kolsky bars, or split Hopkinson bars, which are widely used for obtaining dynamic material properties. Modifications are introduced for obtaining reliable data. Specific experiment design guidelines are provided to subject the specimen to desired testing conditions. Detailed Kolsky-bar examples are given for different classes of materials (brittle, ductile, soft, etc) and for different loading conditions (tension, torsion, triaxial, high/low temperatures, intermediate strain rate, etc). The Kolsky bars used for dynamic structural characterization are briefly introduced. A collection of dynamic properties of various materials under various testing conditions is included which may serve as a reference database. This book assists both beginners and experienced professionals in characterizing high-rate material response with high quality and consistency. Readers who may benefit from this work include university students, instructors, R & D professionals, and scholars/engineers in solid mechanics, aerospace, civil and mechanical engineering, as well as materials science and engineering.

Download or read book A Microcomputer Based System for the High Speed Compression Test by the Split Hopkinson Pressure Bar Technique written by T. Yokoyama and published by . This book was released on 1986 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: A microcomputer-based system has been developed for the high-speed compression test by the split Hopkinson pressure bar technique. The present test system enables one to obtain reliable dynamic stress-strain data for materials for a very short period. The range of strain rates achieved by the test system is approximately 102 to 2 x 103 s-1 depending on the strength of the material and the impact velocity of a striker bar. The accuracy of the entire test system is checked directly by comparing the static and dynamic test results for a strain-rate insensitive material. Test results are presented for tough pitch copper and two aluminum alloys.

Download or read book Dynamic Compression Measurements on Selected Granitic Rocks Using Split Hopkinson Pressure Bar Test written by Rajeev Ranjan and published by . This book was released on 2007 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dynamic strength measurement on rocks has critical applications in areas ranging from blasting and fragmentation to design of underground structures. The present work on selected granitic rocks deals with measurements of compressive strength under dynamic loading conditions using the Split Hopkinson Pressure Bar apparatus. The tests involved two experimental setups with 19 mm and 25 mm diameter bar in order to study the strain-rate effects on dynamic compressive strength. Parametric studies have also been conducted to achieve dynamic stress equilibrium using pulse shapers. The ratio of dynamic compressive strength to static uniaxial compressive strength defined as dynamic increase factor (DIF) was found to be & sim;1.7 at a strain rate of & sim;550/s for Stanstead granite. Similar DIFs were obtained for the Laurentian and Barre granites. It was also noted that the use of pulse shapers can result in considerable reduction in strain rate without always achieving stress equilibrium.
Download or read book The Kolsky Hopkinson Bar Machine written by Ramzi Othman and published by Springer. This book was released on 2018-04-20 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book, leading scientists share their vision on the Kolsky-Hopkinson bar technique, which is a well-established experimental technique widely used to characterize materials and structures under dynamic, impact and explosion loads. Indeed, the Kolsky-Hopkinson bar machine is not a simple experimental device. It is rather a philosophical approach to solve the problem of measuring impact events. The split Hopkinson pressure bar conventional device is mainly limited to test homogeneous ductile non-soft materials under uni-axial compression. Extending the use of this device to more versatile applications faces several challenges such as controlling the stress state within the specimen and mastering the measurement of forces and velocities at the specimen-bar interfaces and then the material properties. Thus, the topics discussed in this book mainly focused on the loading and processing parts.

Download or read book Constitutive Relations under Impact Loadings written by Tomasz Lodygowski and published by Springer Science & Business Media. This book was released on 2013-12-19 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes behavior of materials (ductile, brittle and composites) under impact loadings and high strain rates. The three aspects: experimental, theoretical and numerical are in the focus of interest. Hopkinson bars are mainly used as experimental devices to describe dynamic behavior of materials. The precise description of experimental techniques and interpretation of wave interaction are carefully discussed. Theoretical background refers to rate dependent thermo viscoplastic formulation. This includes the discussion of well posedness of initial boundary value problems and the solution of the system of governing equations using numerical methods. Explicit time integration is used in computations to solve dynamic problems. In addition, many applications in aeronautic and automotive industries are exposed.

Download or read book New Experimental Techniques with the Split Hopkinson Pressure Bar written by and published by . This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The split Hopkinson pressure bar or Kolsky bar has provided for many years a technique for performing compression tests at strain rates approaching 104 s−1. At these strain rates, the small dimensions possible in a compression test specimen give an advantage over a dynamic tensile test by allowing the stress within the specimen to equilibrate within the shortest possible time. The maximum strain rates possible with this technique are limited by stress wave propagation in the elastic pressure bars as well as in the deforming specimen. This subject is reviewed in this paper, and it is emphasized that a slowly rising excitation is preferred to one that rises steeply. Experimental techniques for pulse shaping and a numerical procedure for correcting the raw data for wave dispersion in the pressure bars are presented. For tests at elevated temperature a bar mover apparatus has been developed which effectively brings the cold pressure bars into contact with the specimen, which is heated with a specially designed furnace, shortly before the pressure wave arrives. This procedure has been used successfully in tests at temperatures as high as 1000°C.

Download or read book Dynamic Failure of Materials and Structures written by Arun Shukla and published by Springer Science & Business Media. This book was released on 2009-10-20 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Failure of Materials and Structures discusses the topic of dynamic loadings and their effect on material and structural failure. Since dynamic loading problems are very difficult as compared to their static counterpart, very little information is currently available about dynamic behavior of materials and structures. Topics covered include the response of both metallic as well as polymeric composite materials to blast loading and shock loadings, impact loadings and failure of novel materials under more controlled dynamic loads. These include response of soft materials that are important in practical use but have very limited information available on their dynamic response. Dynamic fragmentation, which has re-emerged in recent years has also been included. Both experimental as well as numerical aspects of material and structural response to dynamic loads are discussed. Written by several key experts in the field, Dynamic Failure of Materials and Structures will appeal to graduate students and researchers studying dynamic loadings within mechanical and civil engineering, as well as in physics and materials science.
