Abstract
The paper presents 3D results on stability of thin-walled cylindrical metal silos made of isotropic rolled and corrugated plates containing bulk solids. The behavior of bulk solids was described using a hypoplastic constitutive model. Nonlinear finite element (FE) analyses with both geometric and material nonlinearity were performed with a perfect and an imperfect silo shell wherein initial geometric imperfections were taken into account in the form of the first eigenmode. The influence of the presence of the bulk solid (sand and wheat) stored during filling on the buckling strength of silos was calculated and compared with that on the strength of the empty silo. Our numerical results indicate a clear strengthening effect of the stored solid on the silo buckling strength.
