Abstract
This paper investigates the collapse behaviour of stiffened panels with a local dent under axial compressive load. The damage on plates is simulated by quasi-static nonlinear FEM, which accounts for the residual stresses caused by a dent and the springback of the stiffened panels. The material properties used in the finite element analysis have been evaluated by tensile tests. To prescribe appropriate boundary conditions, extended stiffened panels with three bays models are adopted in FE analyses. The resistance of the stiffened panels to denting is analyzed first. The effects of residual stress, geometry model and dent depth of stiffened panels on the ultimate strength and the springback of the stiffened panels are analyzed.
