Experimental tests were conducted to determine the failure characteristics of simplified box-type wing structures loaded dynamically, as compared to those of similar beams loaded statically. It was found that under dynamic loading, of the type applied, failure occurred at essentially the same loads and deflections observed at failure under static loading conditions. Tip deflections and accelerations were calculated using the force-deflection relationship determined by static loading, and compared to measured values. Agreement between measured and calculated values was only fair.
