Ceramics CMRG

Ceramics CMRG

Consortium Lead: Prof. Richard Haber (Rutgers)
ARL Lead: Dr. Jerry LaSalvia

The Ceramics CMRG coordinates and oversees all research within the MEDE CRA on ceramics, and particularly on boron carbide as a model lightweight ceramic.

Experimental CTRG: The Ceramics Experimental CTRG focuses on advanced experimental techniques, advanced characterization techniques and in situ methods through both discovery experiments and integrative experiments on boron carbide and its variants.

Modeling CTRG: The Ceramics Modeling CTRG focuses on advanced multiscale modeling and simulation techniques as applied to armor ceramics, as well as new approaches to bridging the scales, with an emphasis on the incorporation of mechanisms and the validation of the models at every scale.

Processing CTRG: The Ceramics Processing CTRG focuses on the design and execution of synthesis and processing routes for boron carbide.

Meetings

These meetings are open to all students, postdocs, PIs, and ARL collaborators from each of the ceramics tasks, but students and postdocs will be required to attend and present at their particular group meeting.

JHU meetings are held in Malone Hall, Room 137.

Remote Access: Please refer to JH Box for information on how to access CMRG meetings and for materials related to these meetings. If you do not have access to JH Box, please contact Katie Vaught at [email protected] to gain access.
