PRACTICE of LOCAL BUCKLING ANALYSIS for THIN FLEXIBLE STRUCTURES

Abstract

In this study, we attempt to use the recent general-purpose finite element code by applying artificial damping from which we can overcome the difficulty in performing the analysis due to local instability. This paper describes the application of the artificial damping technique for the generation of singularities in large-deformed thin flexible structures, including elastic and viscoelastic cylindrical shells and foam materials with microstructure.
