Abstract
AbstractAs a typical thin wall structure, the composite stiffened panel not only has the splendid properties of composite material, but also shows the excellent performance of the composite wall structure with low quality and high bearing capacity. For the structure, the buckling and post-buckling failure of the panel and the effect of damage on the performance of the stiffened panel will happen. Thus, in this paper, the effect of damage on post-buckling bearing capacity of composite stiffened panels under shear load is researched. Three finite element models are built, including no damage shear model, delamination embedded shear model and shear after impact model. The shear failure, effect of delamination and impact damage on panel bearing strength is discussed. Furthermore, the effects of the size of delamination and position of impact on structure performance are also researched. These researches provided abundant theoretical supports for the experiment design and hopeful to be applied in industry manufacturing.KeywordsShear loadDelaminationStiffened panel
