looking to design and hopefully build a micro-tensile tester to test the properties of human hair.
as part of my uni class I need to design the grippers involved and have a look at non contact extensiometers.
Could anyone point me in the right direction with some links or books? or even provide some first hand info?
the problems I can think of atm that I don't have much of an idea how to get about are measurement of the test piece and the fact that the cross sectional area of bio-materials normally reduces dramatically with extension so the could possibly slip out of the grips.
any help would be very appreciated :)
