Abstract
Systems and methods for determining a Material's (“MTL”) mechanical properties. The methods comprise: coupling a first end of MTL to a First Mechanical Mechanism (“FMM”) movable in a First Direction (“FD”) and coupling a second end of MTL to a Second Mechanical Mechanism (“SMM”) movable in a Second Direction (“SD”); applying a first Pulling Force (“PF”) to MTL; applying an Oscillating Force (“OF”) to MTL; applying a second PF to MTL so as to cause any undulations in MTL to be removed and to cause a loading of fibers or polymeric units that support MTL; allowing MTL to oscillate through a series of cycles of loading and unloading; measuring a strain/stress on MTL as a function of time; determining a natural frequency of MTL based on the strain/stress; and determining an elastic modulus of MTL using the natural frequency.
