Abstract
A device that can measure the dynamic compliance of a material has applications for research, health sciences and for use as a pedagogical tool. A device was created which stochastically perturbs a material while measuring the resulting forces and displacements. A software program then creates a non-parameterized impulse response function in addition to a fit second order model for the material. The device was tested on a compliant sponge sample which exhibited highly nonlinear dynamic behavior. The low frequency compliance of the sponge was measured with the device with 16% to 31% error. Improvements for further dynamic testing on the sponge are presented as well as future improvements to the design of the device.
