I conducted a uniaxial tension test for a variety of materials but wasn't able to gather much useful axial strain data due to the extensometer continually slipping. I have axial strain data for the linear elastic region of the stress strain curve and I also have the extension of the crossbar of the machine. Since the materials of the machine are strained and thus stretch a certain amount, the extension data from the crossbar isn't very accurate for determining the strain in the specimen that's being tested. Using Hooke's law, is it possible to determine a modulus of elasticity of the materials in the testing machine, then use that value to calculate the strain of the specimen from the crossbar extension data?
Intuitively I think that it should work, but I'm having trouble verifying it.
Known Data:
σ
εaxial
εextension
