Durability of Ceramic-Matrix Composites presents the latest information on these high-temperature structural materials and their outstanding advantages over more conventional materials, including their high specific strength, high specific modulus, high temperature resistance and good thermal stability. The critical nature of the application of these advanced materials makes it necessary to have a complete understanding of their characterization.

This book focuses explicitly on the durability of CMCs and will be extremely valuable for materials scientists and engineers who are dealing with the simulation of durability response and fatigue of ceramic matrix composites.

Ceramic Matrix Composites: Lifetime and Strength Prediction Under Static and Stochastic Loading focuses on the strain response and lifetime prediction of fiber-reinforced ceramic-matrix composites under stress-rupture loading at intermediate temperatures. Typical damage mechanisms of matrix cracking, interface debonding and oxidation, and fiber's oxidation and fracture are considered in the micromechanical analysis. Effects of composite's constituent properties, peak stress, and testing temperature on the composite's strain response and lifetime are also analyzed in detail.

Finally, a comparison of constant and different stochastic stress spectrum on composite's damage evolution and fracture is discussed. This book will be a practical guide for the material researcher and component designer needing to better understand the composite's damage and fracture behavior under stress-rupture loading at intermediate temperatures.

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.

Ceramic matrix composites (CMCs) can withstand higher temperatures, reduce cooling airflow, improve turbine efficiency, and greatly reduce structural mass compared to the high temperature alloys. This book focuses on the matrix first/multiple cracking, crack opening and closure behavior in CMCs at high temperatures.

While conducting in situ experimental observations to analyze the damage mechanisms and failure modes, the author develops micromechanical damage models and constitutive models to predict the first matrix cracking stress, multiple matrix cracking density, matrix crack opening displacement, and cracking closure stress at high temperatures. The effects of composite’s constituent properties, stress level, and ambient temperature on matrix cracking, opening, and closure are also discussed.

This book will help material scientists and engineering designers to understand and master the matrix cracking and closure behavior of fiber-reinforced CMCs.
