RISMulti-Lead Direct Current Potential Drop Method for In Situ Health Monitoring of Ceramic Matrix Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The method of direct current potential drop (DCPD) can be utilized as an effective and convenient approach for in situ damage detection, and as a nondestructive evaluation technique. We present the results from use of a ...
Monitoring Damage in Nonoxide Composites at High Temperatures Using Carbon-Containing CVD SiC Monofilament Fibers as Embedded Electrical Resistance Sensors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Electrical resistance (ER) has become a technique of interest for monitoring SiC-based ceramic composites. The typical constituents of SiC fiber-reinforced SiC matrix composites, SiC, Si, and/or C, are semiconducive to ...
