Book excerpt: A study was conducted which investigated the behavior of a Nicalon/ Calcium-Aluminosilicate (Nicalon/CAS) cross-ply ((0/90)2S) ceramic matrix composite at elevated temperatures under tension-tension fatigue loading. Tension-tension fatigue tests were performed with a load ratio of R = 0.10 and a frequency of 10 Hertz at 700 deg C and 850 deg C. These results were compared to results from a previous study conducted at room temperature. Material behavior and damage was recorded by fatigue life curves, elastic modulus' maximum and minimum strain, acetate replication techniques, and post-mortem fractography. Analysis of these results showed identical matrix dominated damage behavior at RT and 700 deg C. Ultimate failure was caused by an accumulation of matrix damage, most of which occurred on the first cycle. However, at 8500C, significantly less damage occurred to the matrix and failure was fiber dominated. Fiber debonding was identified as the major damage mechanism responsible for final failure at this elevated temperature.

Book Synopsis Time-Dependent Mechanical Behavior of Ceramic-Matrix Composites at Elevated Temperatures by : Longbiao Li
Download or read book Time-Dependent Mechanical Behavior of Ceramic-Matrix Composites at Elevated Temperatures written by Longbiao Li and published by Springer Nature. This book was released on 2020-04-18 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates the time-dependent behavior of fiber-reinforced ceramic-matrix composites (CMCs) at elevated temperatures. The author combines the time-dependent damage mechanisms of interface and fiber oxidation and fracture with the micromechanical approach to establish the relationships between the first matrix cracking stress, matrix multiple cracking evolution, tensile strength, tensile stress-strain curves and tensile fatigue of fiber-reinforced CMCs and time. Then, using damage models of energy balance, the fracture mechanics approach, critical matrix strain energy criterion, Global Load Sharing criterion, and hysteresis loops he determines the first matrix cracking stress, interface debonded length, matrix cracking density, fibers failure probability, tensile strength, tensile stress-strain curves and fatigue hysteresis loops. Lastly, he predicts the time-dependent mechanical behavior of different fiber-reinforced CMCs, i.e., C/SiC and SiC/SiC, using the developed approaches, in order to reduce the failure risk during the operation of aero engines. The book is intended for undergraduate and graduate students who are interested in the mechanical behavior of CMCs, researchers investigating the damage evolution of CMCs at elevated temperatures, and designers responsible for hot-section CMC components in aero engines.

Book Synopsis Masters Theses in the Pure and Applied Sciences by : Wade H. Shafer
Download or read book Masters Theses in the Pure and Applied Sciences written by Wade H. Shafer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 39 (thesis year 1994) a total of 13,953 thesis titles from 21 Canadian and 159 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 39 reports theses submitted in 1994, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.
Book Synopsis High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites by : Longbiao Li
Download or read book High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites written by Longbiao Li and published by CRC Press. This book was released on 2022-08-09 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on mechanical hysteresis behavior in different fiber-reinforced ceramic-matrix composites (CMCs), including 1D minicomposites, 1D unidirectional, 2D cross-ply, 2D plain-woven, 2.5D woven, and 3D needle-punched composites. Ceramic-matrix composites (CMCs) are considered to be the lightweight high-temperature materials for hot-section components in aeroengines with the most potential. To improve the reliability and safety of CMC components during operation, it is necessary to conduct damage and failure mechanism analysis, and to develop models to predict this damage as well as fracture over lifetime - mechanical hysteresis is a key damage behavior in fiber-reinforced CMCs. The appearance of hysteresis is due to a composite’s internal damage mechanisms and modes, such as, matrix cracking, interface debonding, and fiber failure. Micromechanical damage models and constitutive models are developed to predict mechanical hysteresis in different CMCs. Effects of a composite’s constituent properties, stress level, and the damage states of the mechanical hysteresis behavior of CMCs are also discussed. This book also covers damage mechanisms, damage models and micromechanical constitutive models for the mechanical hysteresis of CMCs. This book will be a great resource for students, scholars, material scientists and engineering designers who would like to understand and master the mechanical hysteresis behavior of fiber-reinforced CMCs.

Book Synopsis Fatigue Behavior of a Cross-Ply Titanium Matrix Composite with Tensile and Zero Mean Load at Elevated Temperature by : S. Mall
Download or read book Fatigue Behavior of a Cross-Ply Titanium Matrix Composite with Tensile and Zero Mean Load at Elevated Temperature written by S. Mall and published by . This book was released on 2006 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fatigue response of a cross-ply [0/90]2S titanium (Ti-15-3) matrix composite reinforced with silicon carbide fibers (SCS-6) was investigated at 427°C. Tension-tension (tensile mean stress) and tension-compression (zero mean stress) loadings were applied. For the same stress range, tension-tension loading caused much lower fatigue lives and greater strain ratchetting than those under tension-compression loading. Despite the longer fatigue lives under tension-compression loading, additional plasticity sites and fatigue damage mechanisms were observed. Fatigue damage mechanisms could be classified into two distinct regimes, independent of mean load, fiber-dominated (fibers fracture prior to matrix cracking) at high-stresses and low-cyclic lives, and matrix dominated (matrix fatigue cracks prior to fiber fracture) at longer lives. Comparisons of the 427°C results are made with previously reported results at room temperature. Deformation mechanisms and fatigue lives were influenced by the testing temperature.
