High-Temperature Mechanical Hysteresis in Ceramic-Matrix Composites

Mechanical hysteresis behavior in fiber-reinforced ceramic-matrix composites (CMCs) is analyzed,with focus on 1D minicomposites,1D unidirectional,2D cross-ply,2D plain-woven,2.5D woven,and 3D needle-punched composites. Damage and failure mechanism analysis is conducted to improve the reliability and safety of CMC components. Micromechanical damage models and constitutive models are developed to predict mechanical hysteresis. The effects of constituent properties,stress level,and damage states are discussed. This book is a valuable resource for students,scholars,material scientists,and engineering designers.

Ceramic-matrix composites (CMCs) are highly sought-after materials for lightweight high-temperature applications in aeroengines due to their exceptional properties. However, their reliability and safety during operation require thorough damage and failure mechanism analysis, as well as the development of models to predict their behavior over time. Mechanical hysteresis is a crucial damage behavior in fiber-reinforced CMCs, and its understanding is essential for improving the performance and longevity of these components.

The appearance of hysteresis in CMCs is attributed to various internal damage mechanisms and modes, including matrix cracking, interface debonding, and fiber failure. To predict mechanical hysteresis in these materials, micromechanical damage models and constitutive models are employed. These models consider the microstructural characteristics of the composites and the interactions between the matrix and fibers.

The effects of composite constituent properties, stress levels, and the damage states on the mechanical hysteresis behavior of CMCs are extensively discussed in this book. It explores the influence of fiber volume fraction, fiber type, matrix properties, and processing techniques on the hysteresis loop shape, energy dissipation, and damage evolution.

Furthermore, the book covers damage mechanisms, damage models, and micromechanical constitutive models for the mechanical hysteresis of CMCs. It provides detailed insights into the mechanisms behind damage initiation, growth, and arrest, as well as the development of effective damage mitigation strategies.

This book is an invaluable resource for students, scholars, material scientists, and engineering designers who seek to understand and master the mechanical hysteresis behavior of fiber-reinforced CMCs. It offers comprehensive coverage of the theoretical foundations, experimental methodologies, and practical applications of mechanical hysteresis in CMCs, enabling researchers and practitioners to advance their knowledge and contribute to the development of innovative and reliable composite materials for aerospace and other industries.
