Available in PDF, EPUB and Kindle. Book excerpt: A thermomechanical analysis of a continuous fiber metal matrix composite (MMC) subjected to cyclic loading is performed herein. The analysis includes the effects of processing induced residual thermal stresses, matrix inelasticity, and interface cracking. Due to these complexities, the analysis is performed computationally using the finite element method. Matrix inelasticity is modelled with a rate dependent viscoplasticity model. Interface fracture is modelled by the use of a nonlinear interface constitutive model. The problem formulation is summarized, and results are given for a four-ply unidirectional SCS-6/[beta]21S titanium composite under high temperature isothermal mechanical fatigue. Results indicate rate dependent viscoplasticity can be a significant mechanism for dissipating the energy available for damage propagation, thus contributing to improved ductility of the composite. Results also indicate that the model may be useful for inclusion in life prediction methodologies for MMC's.

This book was released on 1997 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall program consisted of two distinct phases with objectives: Phase I Objective: To characterize the evolution of isothermal fatigue damage using nondestructive evaluation techniques and correlate this information with residual strength of the composite. Phase II Objective: To characterize and compare the evolution of damage due to creep and TMF fatigue of metal matrix composites (SCS-6/TI-6A1-4V manufactured by Textron Specialty Materials) using nondestructive evaluation techniques and thereby derive an 'inefficiency factor' for damage accumulation under in-phase thermomechanical fatigue (IP-TMF). Phase I Results: The first phase of the program concluded that the usefulness of ultrasonic nondestructive evaluation to assess fatigue damage in a 06 Sigma-1240/Ti-6242 composites has been demonstrated through correlation of immersion and in situ ultrasonic data with residual tensile strength. Immersion surface wave scanning proved to be one of the most promising methods for correlating fatigue damage with the residual tensile strength for the composite used in this study. This study demonstrated that in situ nondestructive ultrasonic longitudinal wave and acoustic emission techniques can monitor the onset and accumulation of damage produced by either sustained loading or in-phased thermomechanical fatigue loading in a titanium matrix composite.

Available in PDF, EPUB and Kindle. Book excerpt: An investigation was undertaken to characterize the deformation response of unidirectional SCS-6/Ti 15-3 metal matrix composite (MMC) lamina subjected to in-phase thermomechanical fatigue (TMF) loading. Evaluations were done in an inert atmosphere to avoid oxidation effects. It was found that the dominant effect on deformation was due to strain ratchetting. Distributed fiber cracking was found to be the primary damage mode in in-phase TMF. The early part of strain ratchetting was identified to be due to the viscoplastic response of the composite as fewer fiber cracks were found to develop at this stage in the MMC specimens. Early fiber cracks were found to occur near molybdenum (Mo) ribbon sites. The fiber-cracking process was determined to be progressive in nature. On qualitative grounds, the concept of fiber ineffective length and the zone of stress intensification at the neighboring fiber at temperature, as in the case of in-phase TMF, was consistent with the observation of progressive fiber cracking in the MMCs.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides the first comprehensive review of its kind on the long-term behaviour of composite materials and structures subjected to time variable mechanical, thermal, and chemical influences, a subject of critical importance to the design, development, and certification of high performance engineering structures. Specific topics examined include damage, damage characterization, and damage mechanics; fatigue testing and evaluation; fatigue behaviour of short and long fibre reinforced polymer and metal matrix materials; viscoelastic and moisture effects; delamination; statistical considerations; the modeling of cumulative damage development; and life prediction. The volume provides an extensive presentation of data, discussions, and comparisons on the behaviour of the major types of material systems in current use, as well as extensive analysis and modeling (including the first presentation of work not found elsewhere). The book will be of special interest to engineers concerned with reliability, maintainability, safety, certification, and damage tolerance; to materials developers concerned with making materials for long-term service, especially under severe loads and environments, and to lecturers, students, and researchers involved in material system design, performance, solid mechanics, fatigue, durability, and composite materials. The scope of the work extends from entry level material to the frontiers of the subject.

This book was released on 2018-08-10 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: A mechanical test technique was developed to assist in quantifying the accumulation of damage in composite materials during thermomechanical fatigue (TMF) cycling. This was accomplished by incorporating definitive elastic mechanical property measurements into an ongoing load-controlled TMF test without disturbing the test specimen or significantly altering the test conditions. The technique allows two fundamental composite properties consisting of the isothermal elastic static moduli and the macroscopic coefficient of thermal expansion (CTE) to be measured and collected as functions of the TMF cycles. The specific implementation was incorporated into the commonly employed idealized in-phase and out-of-phase TMF cycles. However, the techniques discussed could be easily implemented into any form of load-controlled TMF mission cycle. By quantifying the degradations of these properties, tremendous insights are gained concerning the progression of macroscopic composite damage and often times the progression of damage within a given constituent. This information should also be useful for the characterization and essential for the verification of analytical damage modeling methodologies. Several examples utilizing this test technique are given for three different fiber lay-ups of titanium metal matrix composites. Castelli, Michael G.

This book was released on 1990 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal matrix composites (MMCs) are rapidly becoming strong candidates for high temperature and high stiffness structural applications such as the Advanced Tactical Fighter (ATF). This study systematically investigated the failure modes and associated damage in a cross-ply, (0/90)2s SCS6/Ti-15-3 metal matrix composite under in-phase and out-of-phase thermomechanic fatigue. Initiation and progression of fatigue damage were recorded and correlated to changes in Young's Modulus of the composite material. Experimental results show an internal stabilization of reaction zone size but degradation and separation from constituent materials under extended cyclic thermal loading. Critical to damage were transverse cracks initiating in the 90 degrees plies, growing and coalescing from fiber/matrix interfaces internal to the specimen, progressing outward through the 0 degree plies before failure. Maximum mechanical strain at failure was determined to be approximately 0.0075 mm/mm. A correlation was made relating maximum matrix stress to failure life, resulting in a fatigue threshold limit of 280 MPa. An attempt was made to correlate the degradation in Young's Modulus (Damage=1-E/Eo) with the applied life cycles from different TMF tests.

This book was released on 2021-06-08 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the relationships between tensile damage and fracture, fatigue hysteresis loops, stress-rupture, fatigue life and fatigue limit stress, and stochastic loading stress. Ceramic-matrix composites (CMCs) possess low material density (i.e., only 1/4 - 1/3 of high-temperature alloy) and high-temperature resistance, which can reduce cooling air and improve structure efficiency. Understanding the failure mechanisms and internal damage evolution represents an important step to ensure reliability and safety of CMCs. This book investigates damage and fracture of fiber-reinforced ceramic-matrix composites (CMCs) subjected to stochastic loading, including: (1) tensile damage and fracture of fiber-reinforced CMCs subjected to stochastic loading; (2) fatigue hysteresis loops of fiber-reinforced CMCs subjected to stochastic loading; (3) stress rupture of fiber-reinforced CMCs with stochastic loading at intermediate temperature; (4) fatigue life prediction of fiber-reinforced CMCs subjected to stochastic overloading stress at elevated temperature; and (5) fatigue limit stress prediction of fiber-reinforced CMCs with stochastic loading. This book helps the material scientists and engineering designers to understand and master the damage and fracture of ceramic-matrix composites under stochastic loading.
