Development of Force-Limiters for Experimental Purposes Presenter(s)

Force-displacement tests are commonly used when studying the mechanics of brain tissue. These tests can help scientists learn more about properties like elasticity and viscoelasticity, which can give greater insight into the reasons for traumatic brain injury as well as the conditions that cause it. However, it is hard to run these tests because of the difficulty of regulating the amount of force exerted on the samples being tested. Certain tests require constant or increasing force to be exerted on samples of brain tissue, and it is possible that too much force can be applied, damaging the equipment used to exert the force and sample used in the experiment. In order to prevent this from happening as often, a force limiter is to be designed using Euler’s critical load equation. This force limiter is intended to break under a certain amount of force, which stops the equipment from damaging itself and the sample. The force limiter was designed in Solidworks and printed from IP-S resin in a nanoscribe printer.
