Download or read book Fatigue of Materials at Very High Numbers of Loading Cycles written by Hans-Jürgen Christ and published by Springer. This book was released on 2018-11-19 with total page 624 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the final reports of the scientific projects funded within the DFG-SPP1466 and, hence, provides the reader with the possibility to familiarize with the leading edge of VHCF research. It draws a balance on the existing knowledge and its enhancement by the joint research action of the priority program. Three different material classes are dealt with: structural metallic materials, long-fiber-reinforced polymers and materials used in micro-electro-mechanical systems. The project topics address the development of suitable experimental techniques for high-frequency testing and damage monitoring, the characterization of damage mechanisms and damage evolution, the development of mechanism-based models and the transfer of the obtained knowledge and understanding into engineering regulations and applications.
Download or read book Toward Assessing the Effects of Crack Front Curvature CFC written by JL. Swedlow and published by . This book was released on 1972 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crack front curvature (CFC) is shown to affect the K calibration of four special geometries for which analysis is currently practicable. The inference is drawn that assuming straight crack fronts in, say, test specimens having non-zero CFC may be non-conservative; the aim of this paper is to initiate further investigation of the effects of CFC.
Download or read book The Impact of Microstructural Interactions Closure and Temperature on Crack Propagation Based Lifing Criteria written by WJ. Evans and published by . This book was released on 1996 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper addresses the problem of predicting crack development at a stress concentration feature from simple laboratory crack growth data. It uses a specifically designed double edge notch geometry as a test vehicle and growth rates generated on standard corner crack and compact tension specimens. A coarse-grained, near-alpha titanium alloy is employed to emphasize any microstructural interaction effects. The bulk of the work is at ambient temperature with a small amount of data obtained at 300°C. It is shown that at low stress (350 MPa), conventional fracture mechanics, without an allowance for crack closure, can correctly predict both crack shape development and cyclic life. The only significant errors occur when the crack front is retarded by prior beta or alpha colony boundaries. These tend to lead to pessimistic predictions. At 550 MPa, however, there is significant notch root plasticity that induces crack closure. An allowance for notch closure in the numerical procedures permits a more accurate prediction of crack shape and cyclic life at this stress level. To support the computer models, a detailed assessment of closure is made using potential difference (PD), strain gage, and replica techniques.

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

Available in PDF, EPUB and Kindle. Book excerpt: Small structures of the micro/nanometer scale, such as electronic/optic devices and MEMS/NEMS have been developed, and the size of their elements now approaches the nano/atomic scale. This book discuses the fracture behavior of nano/atomic elements (nanofilms, nanowires, and so on) and focuses on the initiation and propagation of interface crack and mechanical instability criterion of atomic structures. This covers the fundamentals and the applicability of the top-down (conventional fracture mechanics to nanoscale) and bottom-up (atomic mechanics including ab initio simulation) concepts. New areas, such as multiphysics characteristics of nanoelements, are introduced as well.

Download or read book Computational Mesomechanics of Composites written by Leon L. Mishnaevsky, Jr and published by John Wiley & Sons. This book was released on 2007-08-20 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical properties of composite materials can be improved by tailoring their microstructures. Optimal microstructures of composites, which ensure desired properties of composite materials, can be determined in computational experiments. The subject of this book is the computational analysis of interrelations between mechanical properties (e.g., strength, damage resistance stiffness) and microstructures of composites. The methods of mesomechanics of composites are reviewed, and applied to the modelling of the mechanical behaviour of different groups of composites. Individual chapters are devoted to the computational analysis of the microstructure- mechanical properties relationships of particle reinforced composites, functionally graded and particle clusters reinforced composites, interpenetrating phase and unidirectional fiber reinforced composites, and machining tools materials.
