I am looking information on how to calculate strain rate in tensile testing if I only can control crosshead speed.
Thanks

where Lo is the initial gage length of the specimen.

You should be able to ignore it and consider the frame infinitely stiff.

What you say may be valid for a standard tensile test, but doesn't apply to all cases. Slow strain rate tensile tests are corrected for machine compliance, as specified in NACE TM0198.

This is also true in tensile work. The frame should be 1000x as stiff as anything else in the system, but the extensions and grips are another issue.
