Features of the numerical calculation of separately standing chimneys in software packages (analysis of the female sex)

Abstract


The following different calculation schemes for modeling free-standing chim­neys were considered: rod scheme, which uses a cantilever rod with constant cross section: ideal cylindrical shell model, analyzed with the ANSYS Workbench 14.0 software package; ideal cylindrical shell model that considers the base, created in the ANSYS Workbench 14.0 software package, and also non-ideal cylindrical shell model with a geometric deviation in form of a dimple. The obtained values of the equivalent stress (von Mises stress - σeq) for the perfect shell in PC ANSYS were compared with the principal stresses (σx), which were defined analytically as equiva­lent stresses (σeq) both for the ideal and for the dimple model. The comparison showed a discrepancy of 15% between the values for the perfect shells and 65% for the concave shell.
