An experimental investigation was conducted to evaluate the significance of warping deformations in the dynamic response of an aircraft seat-type structure subjected to impact loading. The test article design featured thin-walled open-section beams and was loaded inertially by a number of rigid weights which were attached to the seat frame. Strain gage data acquired during these tests were analyzed to whether these data are better represented by Vlasov beam theory or Euler-Bernoulli beam theory. Static tests of the test article were also conducted to validate the data reduction techniques employed in the analysis of the dynamic data.
