Three-Dimensional Finite Element Analysis for Pressure on Flexible Wall Silos

A 3D finite element model (FEM) for predicting the distribution of lateral pressure in a square flexible walled steel silo during filling phase was analyzed this study. The numerical approach, developed using Abaqus software, predicts stress state bulk solids, as well pressures exerted on walls. An elasto-plastic Drucker–Prager criterion employed to simulate behavior granular materials. FEM simulates solid and its interaction with silo’s wall base surface-to-surface discretization model. model’s predictions were validated by previous experimental measurements. results revealed good agreement between research confirms that is not uniform at any level. This highlights fact many available theories current design codes are accurate As result wall’s deformability, regimes change significantly horizontal direction showed variations drastically regard stiffness. has been used investigate effect critical parameters distribution, such properties thickness, type, whether deep or flat.
