EFFECTS OF THERMAL LOADS ON AGRICULTURAL SILOS

Abstract eng:
The objective of this work is to perform an analysis of pressure distributions in grain silos subjected to thermal effects. To this end, the commercial ANSYS program, based on the finite-element method is employed. Changes in the temperature along the silo walls produce dilatations and contractions, which cause variations both in the wall stresses and in the grain pressures. These dilatations and contractions increase the Young’s modulus of the grain, causing the stresses on the silo walls during the contractions to rise with each new cycle.
