Download or read book Experimental Determination of the Dependence of Crack Extension Force on Crack Length for a Single edge notch Tension Specimen written by John E. Srawley and published by . This book was released on 1964 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The single-edge-notch form of a plane-strain (or opening mode) crack toughness specimen is particularly economical in regard to available test material and testing machine capacity. The necessary calibration relation for a particular design of a single-edge-notch specimen centrally loaded in tension, was determined from a series of compliance measurements at crack lengths ranging from zero to one-half the specimen width. The accuracy of the calibration is estimated to be +1/2 percent in the range of interest. Agreement with concurrent results obtained by boundary collocation of an appropriate stress function is excellent. Alternative types of specimen are discussed, and the relation between necessary specimen size and the ratio of toughness to yield strength is emphasized.

This book was released on 2012-12-06 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes the edited proceedings of the Advanced Studies Institute on Boundary Element Techniques in Computer Aided Engineering held at The Institute of Computational Mechanics, Ashurst Lodge, Southampton, England, from September 19 to 30, 1984. The Institute was held under the auspices of the newly launched "Double Jump Programme" which aims to bring together academics and industrial scientists. Consequently the programme was more industr ially based than other NATO ASI meetings, achieving an excellent combination of theoretical and practical aspects of the newly developed Boundary Element Method. In recent years engineers have become increasingly interested in the application of boundary element techniques for'the solution of continuum mechanics problems. The importance of boundary elements is that it combines the advantages of boundary integral equations (i.e. reduction of dimensionality of the problems, possibility of modelling domains extending to infinity, numerical accura'cy) with the versatility of finite elements (i.e. modelling of arbitrary curved surfaces). Because of this the technique has been well received by the engineering and scientific communities. Another important advantage of boundary elements stems from its reduction of dimensionality, that is that the technique requires much less data input than classical finite elements. This makes the method very well suited for Computer Aided Design and in great part explains the interest of the engineering profession in the new technique.

Available in PDF, EPUB and Kindle. Book excerpt: This multiauthor volume provides a useful summary of current knowledge on the application of fracture mechanics to composite materials. It has been written to fill the gap between the literature on fundamental principles of fracture mechanics and the special publications on the fracture properties of conventional materials, such as metals, polymers and ceramics.The data are represented in the form of about 420 figures (including diagrams, schematics and photographs) and 80 tables. The author index covers more than 500 references, and the subject index more than 1000 key words.

Download or read book On the Experimental Calibration of a Potential Drop System for Crack Length Measurements in a Compact Tension Specimen written by G. Belloni and published by . This book was released on 2002 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present study was focused on the setup of a system for monitoring deep cracks in notched specimens in creep and fatigue laboratory tests. The test configuration features, the instrumentation requirements, and the important problems of the calibration for potential drop application to both fatigue and creep crack growth tests on compact tension specimens are discussed in detail. Experimental tests on the compact tension specimen geometry were carried out at ambient and high temperatures in order to define and validate an experimental calibration for this specimen geometry, to check the effect of temperature, and to compare the crack growth calibration curves under creep or fatigue conditions.

Download or read book The Influence of Plasticity on Crack Length Measurements Using the Potential Drop Technique written by K. M. Tarnowski and published by . This book was released on 2015 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential drop (PD) technique is one of the most common methods for determining crack growth; however, other factors can also change the resistance of the specimen, which may erroneously be interpreted as crack extension. In tough, ductile materials, plastic strain can cause a significant change in PD. This paper presents an experimental investigation which quantifies the apparent crack extension due to strain prior to the onset of physical crack growth and considers ways to mitigate it. Compact tension, C(T), and single edge notch tension, SEN(T), specimen geometries are considered with a range of crack lengths. The influence of probe location is also considered. The results identify apparent crack extensions of up to 1.0 mm in the absence of any physical crack extension. This can be reduced through careful selection of probe locations. Appropriate locations are suggested for the geometries considered. It is also shown that high constraint geometry can significantly reduce the influence of plasticity on PD.
