GS17 Damage Identification of Sandwich Panels
Details
This study proposes a method for identifying damages induced by an impact force acting on aluminum and CFRP sandwich panels with honeycomb core. The impact location and the impact history are identified using strain data measured by biaxial strain gauges. Experimental transfer matrices, which relate the impact force and the sensor response, are used to identify the force history. The present paper reveals that the impact damage in aluminum and CFRP sandwich panels can be estimated by the shape and the peak value of identified force history of the impact force.
