In this study, for the first time, we present a shell finite element based on positions and generalized vectors for instability analysis of thin-walled members. The presence of generalized vectors and transverse strain enhancement guarantee to the pr

The importance of knowing critical loads and post-critical behavior of thin-walled structures motivates the development of several scientific and practical studies. Most references are concerned with stability analysis for small displacements (first

In this study, we develop and propose a finite element (Box Element) designed specially to improve the shell-based simulation of elastic thin-walled structures. The Box Element (BE) allows a simple and automatic connection between beams and columns,
