How Can I Design a Micro-Tensile Tester for Human Hair?

Click For Summary
SUMMARY

This discussion focuses on designing a micro-tensile tester specifically for evaluating the mechanical properties of human hair. Key considerations include the design of grippers and the use of non-contact extensiometers to accurately measure tensile properties. Participants highlight challenges such as the significant reduction in cross-sectional area of bio-materials during extension, which may lead to slippage from grips. The need for reliable measurement techniques and resources for further information is emphasized.

PREREQUISITES
  • Understanding of micro-tensile testing principles
  • Familiarity with non-contact extensiometers
  • Knowledge of material properties of bio-materials
  • Experience in designing mechanical grips for testing
NEXT STEPS
  • Research the design principles of micro-tensile testers
  • Explore non-contact extensiometer technologies and their applications
  • Investigate methods for measuring the mechanical properties of bio-materials
  • Study grip design techniques to prevent slippage during tensile testing
USEFUL FOR

Students in engineering and materials science, researchers in biomechanics, and professionals involved in testing and analyzing the properties of biological materials will benefit from this discussion.

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 :)

Hi there
Even i am doing a very similar project. Could you please help me with it.
