CLaMMP - Central Laboratory for Materials Mechanical Properties

The Central Laboratory for Materials Mechanical Properties (CLaMMP) contains mechanical testing machines and accessories for conducting educational, research, and outreach experiments on most solid materials. The lab is available for use for both the Northwestern community and non-Northwestern researchers on an hourly-fee basis. The laboratory is directed by Prof. David Dunand and is managed by Mark Seniw.
