Abstract

In this paper, a large-scale composite thin-walled stiffened structure is subjected to an axial compression stability test. The stability of the structure is tested and analyzed using resistance strain gauges, digital speckle correlation and finite element methods. The analysis results were analyzed from four aspects: instability load, load strain result, load displacement result and test calculation result comparison. In this paper, the initial buckling load, load-strain bifurcation curve, buckling wave distribution characteristics of the composite thin-walled stiffened curved plate under two radius parameters, the comparison of the test deformation results and the calculation analysis results, etc. are obtained for research. The research on the stability of large-scale composite thin-walled reinforced structures provides new ideas and methods.
