This book was released on 2018-10-28 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of the acoustic emission (AE) technique to locate and monitor damage growth in titanium matrix composites (TMC) was investigated. Damage growth was studied using several optical techniques including a long focal length, high magnification microscope system with image acquisition capabilities. Fracture surface examinations were conducted using a scanning electron microscope (SEM). The AE technique was used to locate damage based on the arrival times of AE events between two sensors. Using model specimens exhibiting a dominant failure mechanism, correlations were established between the observed damage growth mechanisms and the AE results in terms of the events amplitude. These correlations were used to monitor the damage growth process in laminates exhibiting multiple modes of damage. Results revealed that the AE technique is a viable and effective tool to monitor damage growth in TMC. Bakuckas, J. G., Jr. and Prosser, W. H. and Johnson, W. S.

This book was released on 1989 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Damage initiation and accumulation has been monitored through acoustic emission (AE) in several center-notched unidirectional metal matrix composites (MMC) and multidirectional boron/aluminum (B/A1) laminates subjected to uniaxial quasi-static tensile loading. Emphasis has been placed on establishing the correlation between the actual damage initiation and growth and AE results. The correspondence between failure processes in the different material systems and the event intensities was investigated, and the results on the event amplitudes are reported. Effect of heat treatment on the failure process and on the associated emission in unidirectional and quasi-isotropic B/Al laminates has also been studied. Notch-tip damage growth was monitored in real-time through optical observations, and effective notch-tip damage extension was determined by applying the compliance matching procedure. Fracture surface morphology was examined via the scanning electron microscope. It is shown that the failure processes in the different material systems can be correlated with the AE event amplitudes. The results indicate that an excellent correlation can be established between the rate of damage growth and the AE results. Thus, it is concluded that AE technique can monitor damage formation and accumulation in MMC in real-time.

Available in PDF, EPUB and Kindle. Book excerpt: This book introduces readers to the application of fracture mechanics and mesomechanics to the analysis of the fracture behaviors of wood and bamboo. It presents a range of research methods to study the fracture behaviors of wood and bamboo, taking into account their various fracture mechanisms resulting from differences in their macroscopic and microscopic structures. It combines theoretical analysis with experiments, as well as various mathematical tools and experimental approaches. The research methods are illustrated by simple schematic diagrams, and the results obtained are largely presented as tables and figures, helping to make the book concise and compact. As such, it provides a valuable guide to the development of new biocomposites that possess exceptional strength and toughness properties and successfully overcome the shortcomings of biomaterials.
