Micromechanics of Ceramic-Matrix Composites at Elevated Temperatures

Ceramic-matrix composites (CMCs) possess high specific strength and modulus at elevated temperature, and have already been applied in hot-section components in aero-engines. To ensure the operation reliability and safety of CMCs components, it is necessary to understand the micro damage mechanisms and internal damage state in the composites. This book focuses on the micromechanics of CMCs at elevated temperatures, including, the stress-strain behavior, proportional limit stress, residual strength, mechanical hysteresis, interface damage, strain response, and lifetime of CMCs at elevated temperatures. This book can help the material scientists and engineering designers to better understand and master the micromechanics of CMCs at elevated temperatures.

Focuses on micromechanics of ceramic-matrix composites at elevated temperatures Proposes micromechanics damage models of ceramic-matrix composites at elevated temperatures Explains micro damage mechanisms and internal damage state in the composites
