The Role of Adhesion and Friction in the Buckling Behavior of Spherical Shells
Please login to view abstract download link
Thin shells are highly sensitive to large deformations, even under relatively small loads, making precise control of their shape and load distribution essential for maintaining stability and optimizing performance in various applications. This study explores the combined effects of adhesion and friction on the buckling behavior of spherical shells. The results demonstrate that increasing adhesion progressively delays buckling, until reaching a critical adhesion threshold where buckling is completely suppressed. A comprehensive buckling phase diagram is presented, mapping the boundary between buckling and non-buckling zones, thereby providing practical design insights for applications requiring buckling control or suppression.
