摘要

Abstract

To investigate the bending instability and wrinkling characteristics of thin-walled circular tubes reinforced with pads

a three-dimensional finite element model of the thin-walled tube was developed

followed by an eigenvalue buckling analysis. The influence of the geometric parameters of the thin-walled tube on the buckling factor and buckling modes was analyzed. The study found that the length of the pad has a significant impact on the load-bearing capacity; results indicate that a longer pad leads to a lower load-bearing capacity of the thin-walled tube. As the thickness of the pad increases

the buckling factor of the thin-walled tube generally shows a decreasing trend. Conversely

as the angle of the pad increases

the buckling factor generally exhibits an increasing trend.
