eTester Presentation Slide

Final Showcase

The following video demonstrates the eTester in action! As you can see, it calculates the elastic modulus of the acrylic sample as 2.3 GPa. This is within the range given by the standard range of Elastic modulus for acrylic. An important result is also that the impact level doesn't affect the frequency readout. This means that the system is truly measuring the fundamental resonant frequency of the material sample, and not the sound of the hit.
