Abstract: Numerical simulation, analytical calculation and experimental research on the shear stability of composite stiffened panels with openings are carried out, verifying the accuracy of the finite element simulation analysis in this paper. Through numerical simulation, the influence of different stringer configurations on the stress concentration at the openings and the shear stability is studied. The relevant conclusions can provide technical references for the structural design of composite stiffened panels with cutout.

Key words: composite, stringer reinforced panel, cutout, stress concentration, buckling
