Abstract: We investigate the effect of defect geometry in dictating the sensitivity of the critical buckling conditions of spherical shells under external pressure loading. Specifically, we perform a comparative study between shells ...

Abstract: We perform numerical experiments using the finite element method (FEM) to investigate the effect of defect–defect interactions on the pressure-induced buckling of thin, elastic, spherical shells containing two dimpled ...

Abstract: Abstract. Geometric imperfections are the primary cause of the pronounced reduction in the buckling load of cylindrical shells subjected to axial compression. Localized defects, which are commonly introduced during ...
