This indentation apparatus was built to assist with the study performed at UMass Dartmouth and consequently published in the Journal of Polymers and the Environment. The objective was to design and build an indentation testing apparatus that can make indents accurate to one micron and measure the resulting reaction force while gathering and recording data.
•LabVIEW coding for actuator control and data gathering
•Microsoft Excel for data analysis
•Proper lathe, milling, tap and die operation
Components and Materials Used
•Physik Instrumente C-863 controller
•Physik Instrumente M235.2DG actuator
•FUTEK LSB200 load cell
•Keithley 2000 Multimeter
•Diamond indenter tip
•Steel and aluminum stock, PVC tubing, bungee cords
The apparatus is capable of making indents accurate to one micron. It can find Young’s modulus of a material at depths equal to or greater than 40 microns. The shock mount effectively dissipates noise that could interfere with the data. Data gathered with this apparatus can be found published in the Journal of Polymers and the Environment.
