Dynamic Mechanics of Materials Laboratory

About DMML
The Dynamic Mechanics of Materials Laboratory at The Ohio State University specializes in mechanical characterization (deformation and failure) of materials over a wide range of strain rates and temperatures. Tension, compression, and shear experiments at strain rates ranging from 10-4 to 104 s-1 and temperatures ranging from -150 oC to 1000 oC can be conducted. The laboratory is equipped with high-quality instrumentation for measuring loads (forces and moments) and deformation (strain).
