Beschreibung

Ceramic-matrix composites (CMCs) are high-temperature structural materials, with outstanding advantages such as high specific strength, high specific modulus, high temperature resistance and good thermal stability, which play a crucial role in the development of high thrust weight ratio aero engines. The critical nature of the application of these advanced materials makes complete characterization a necessity. Designers must have information pertaining to not only the strength of the material, but also its fatigue and damage characteristics. Nonlinear Damage Behavior of Ceramic Matrix Composites will help the reader [researchers, material scientists and design engineers] to understand more deeply about the damage mechanisms inside CMCs, in order to better design components used in aeronautics and astronautics. Key areas addressed in the book include: the nonlinear damage behavior of ceramic-matrix composites, including damage mechanisms and models, nonlinear damage behavior of ceramic-matrix composites under tensile and fatigue loading, strain-rate dependent, stochastic loading dependent, and time dependent nonlinear damage behavior, and the effect of pre-exposure and thermal fatigue on non-linear damage behavior of ceramic-matrix composites.


- Comprehensive coverage of damage mechanisms and models under tensile and cyclic fatigue loading, which ultimately control nonlinear behavior
- Covers nonlinear damage analysis of CMC components and experimental observation of damage evolution
- Provides extensive knowledge on fracture mechanic principles used in the design of aerospace propulsion systems
