    Abstract: A method is disclosed of using external polymeric analytical techniques to predict in-vivo polymeric performance, more particularly, viscoelastic property characterization for performance modeling of biomedical devices that incorporate a polymeric component and are load-bearing during service. Time-Temperature Superposition can be used to accelerate external testing of pertinent properties. Boltzmann's superposition provides a mathematical methodology for determining the time-dependent strain that develops in response to an imposed stress history. The modeling of the present invention provides an opportunity to describe and predict behavior of the device during in-vivo service, as well as it providing a basis for evaluating alternate “candidate” polymers for use in the construction of the device.

    Abstract: A control system for a failure mode testing system is described. The control system employs at least one control algorithm that enables the testing system to be operated at optimal pressure and frequency levels in order to generate a desired system response, such as a desired energy level and desired slope of the fast Fourier transform of the system response. Also described are a pressure dither system and a frequency ringing system for enhancing the operation of the actuator cylinders of the failure mode testing system. All three of the systems can be incorporated, either singularly or in combination, into a computer software program that can be employed to operate and control the failure mode testing system.

    Abstract: A method and method of estimating fatigue life of a structure is disclosed. In one embodiment, the method may include determining strain on the structure using a plurality of gauges positioned on the structure. The method may also include detecting a parameter of the structure with a plurality of sensors positioned on the structure. Further, the method includes converting the detected parameter and the determined strain to proportional loads acting on the structure and transforming the proportional loads to coordinate system data associated with the structure. Based on the coordinate system data, the fatigue life of the structure may be estimated.
