Repeated Buckling Tests of Stiffened Thin Shear Panels
Abstract
An experimental study of repeated buckling of shear panels, which represents the first phase of a more comprehensive program is presented. Two similar typical Wagner beams were tested under cyclic loading not exceeding 70% of the predicted ultimate static load, one tested as a cantilever and one loaded symmetrically at three points. The aim of these pilot tests was better understanding of the physical phenomena and evaluation of the experimental methods for future tests. The appropriate location and precautions for use of strain gages to measure the stress concentrations at the edges of the diagonal of tension were determined, and the suitability of the shadow moire technique for deflection measurements was ascertained. It was found that cyclic loading at a fairly high load level causes significant structural changes in the shear panels that affect the failure of the beam.
