Research Currently in Progress

  • Measuring nonlinear displacement and strain response at sparse measurement locations and to predict model full space response (displacement and strain) using linear modal modeling approaches
  • Developing time, frequency and modal approaches to neutralize the effects of testing differences moving from the field environment to the laboratory environment; goal is to provide realistic vibration testing profiles mimicking the field response in the laboratory.
  • Utilizing optical displacement and strain measurements with motion magnification to predict full field response from limited line of sight measurements.
  • Incorporating strain profiles in vibration testing feedback loop to achieve realistic damage for device under test response.
