This book focuses on the vibration behavior of ceramic-matrix composites
(CMCs), including (1) vibration natural frequency of intact and damaged
CMCs; (2) vibration damping of CMCs considering fibers debonding and
fracture; (3) temperature-dependent vibration damping of CMCs; (4)
time-dependent vibration damping of CMCs; and (5) cyclic-dependent
vibration damping of CMCs. Ceramic-matrix composites (CMCs) possess low
material density (i.e., only 1/4 or 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. Relationships between microstructure, damage mechanisms,
vibration natural frequency, and vibration damping of CMCs are
established. This book helps the material scientists and engineering
designers to understand and master the vibration behavior of CMCs at
room and elevated temperatures.
