Buckling and post-buckling of thin-walled stiffened panels: modelling imperfections and joints
https://orcid.org/0000-0002-6033-4024
Abstract This paper explores the effect of different modelling strategies to represent geometrical imperfections and joints in flat thin-walled stiffened panels during buckling and post-buckling. Compression tests were performed on aircraft grade aluminium alloy panels jointed to L-shape stiffeners using rivets with digital image correlation used to monitor out-of-plane deformations, mode shape changes and failures such as stiffener debonding. Experiments were replicated using finite element analysis employing different levels of complexity to model geometric imperfections and joints. The advantages and limitations of these strategies are discussed and recommendations are made.
Highlights Joints and imperfections can strongly affect the structural response during buckling and postbuckling. Experimental compression tests are used to obtain both global and local behaviour. Different Finite Element modelling strategies are used to understand the role of imperfections and joints in the structural response. Advantages and limitations of the technique used are presented.
