System Design and Selection P 09045: Membrane Characterization Test Stand

Project Summary Purpose: Create test stand for measuring physical properties (stress/strain) of artificial materials Reason: Stress/strain data from current uniaxial test stand does not have known relationship ◦ Summer Research shows that correlation attempts with membrane indenter are futile P 09045: Membrane Characterization Test Stand 12/12/2021 4

Project Summary Objectives • Establish what type of loading will be most efficient and beneficial • Develop a cost effective design • Keep the design simple, yet advanced enough to maintain accuracy • Control strategy through Lab. VIEW interface • Ensure multiple types of materials can work with fixture P 09045: Membrane Characterization Test Stand 12/12/2021 5

Project Summary Benefits • Apply to thesis research project currently in progress • Future senior design groups can build upon the loading system and increase machine efficiency and ability • Allow for future courses in the bioengineering program or mechanics labs to use a different type of loading machine to depict a stress/strain relation P 09045: Membrane Characterization Test Stand 12/12/2021 6
