Available in PDF, EPUB and Kindle. Book excerpt: Moire interferometry with line densities of 1200 and 40 lines per mm was used to determine the two orthogonal displacements surrounding a stably extending crack in a 2024-T3 aluminum alloy, single edge cracked specimen. The test protocol consisted of using the fine moire grating prior to and up to the onset of crack extension and the coarse moire grating for the ensuing crack extension up to delta a = 6 mm. The displacement fields were used to compute the J-integrals for various contours during crack tip blunting and crack extension. As expected, the far-field J-integral value prior to stable crack growth coincided with the LEFM strain energy release rate, G, and validated the experimental Procedure. However, the J values obtained from the near tip contour increased slowly while the far field J values increased rapidly with increasing stable crack growth. The HRR displacement field was computed from the experimentally determined far field J. The HRR displacement field agreed with the measured displacement field prior to stable crack growth since J = G. However, the HRR horizontal displacement field progressively deviated from the measured values with crack extension.

Book Synopsis J-Integral and HRR Field of a Stably Growing Crack, an Experimental Analysis by : Mahyar S. Dadkhah
Download or read book J-Integral and HRR Field of a Stably Growing Crack, an Experimental Analysis written by Mahyar S. Dadkhah and published by . This book was released on 1990 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: The displacement fields surrounding stably growing cracks in 7075-T6, 2024-0, 2024-T3, 5052-H32 and 2091 aluminum alloy, standard and cruciform, single-edge notched (SEN) specimens were determined by Moire interferometry. An approximate and exact J-integral values were determined and found to be within 5% of each other and were both path independent. The associated HRR crack tip displacements in all specimens were in agreement with the measured displacements vertical to the crack but consistently differed in magnitude and order of singularity with the measured displacements parallel to the crack. One of the most popular ductile fracture criterion of the past two decades is the J-integral concept (1) for which enormous developmental efforts have been expended in recent years. The J-integral is heralded by many as a stable crack growth and ductile fracture criteria since in its linearly elastic limit, it reduces to the elastic strain energy release rate. (kr).

Book Synopsis T?* Integral Under Plane Stress Crack Growth by : Y. Omori
Download or read book T?* Integral Under Plane Stress Crack Growth written by Y. Omori and published by . This book was released on 1997 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: The T?* integral values associated with stable crack growth in A606 HSLA steel SEN specimens were determined experimentally and numerically. The displacement fields obtained through Moiré interferometry and elastic-plastic finite element analysis were used to evaluate T?* associated with the moving crack tip. T?* decreased with the reduction in the size of the integration contour, T?, and continually increased with stable crack growth in this specimen. The measured and computed crack-tip opening angle (CTOA), on the other hand, was a constant 15° during stable crack growth after dropping from the measured and computed initial high values of 35 and 57°, respectively.

Book Synopsis Strength and Toughness of Materials by : Toshiro Kobayashi
Download or read book Strength and Toughness of Materials written by Toshiro Kobayashi and published by Springer Science & Business Media. This book was released on 2004-03-04 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the shift from the Metal Age progresses, materials engineers and materials scientists seek new analytical and design methods to create stronger and more reliable materials. Based on extensive research and developmental work done at the author’s multi-disciplinary material laboratory, this graduate-level and professional reference addresses the relationship between fracture mechanisms (macroscale) and the microscopic, with the goal of explaining macroscopic fracture behavior based on a microscopic fracture mechanism. A careful fusion of mechanics and materials science, this text and monograph systematically considers an array of materials, from metals through ceramics and polymers, and demonstrates lab-tested strategies to develop desirable high-temperature materials for technological applications.

Both the United States and Japan are at the forefront of the re search on fracture mechanics and its applications to fracture prevention. Dur ing the past few years, major research efforts have been made in the areas of non-linear fracture mechanics and its applications to fracture initiation, slow crack growth, creep and fatigue. This joint seminar offered an unique opportunity for detailed exchange of information on current researches and fu ture efforts.
Book Synopsis Finite Elements in Fracture Mechanics by : Meinhard Kuna
Download or read book Finite Elements in Fracture Mechanics written by Meinhard Kuna and published by Springer Science & Business Media. This book was released on 2013-07-19 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fracture mechanics has established itself as an important discipline of growing interest to those working to assess the safety, reliability and service life of engineering structures and materials. In order to calculate the loading situation at cracks and defects, nowadays numerical techniques like finite element method (FEM) have become indispensable tools for a broad range of applications. The present monograph provides an introduction to the essential concepts of fracture mechanics, its main goal being to procure the special techniques for FEM analysis of crack problems, which have to date only been mastered by experts. All kinds of static, dynamic and fatigue fracture problems are treated in two- and three-dimensional elastic and plastic structural components. The usage of the various solution techniques is demonstrated by means of sample problems selected from practical engineering case studies. The primary target group includes graduate students, researchers in academia and engineers in practice.
