AN ENDOCHRONIC FINITE-ELEMENT MODEL FOR PREDICTING LOADS IN GRAIN STORAGE STRUCTURES

A finite element algorithm was developed using an endochronic constitu tive model to predict loads in grain storage bins. Triaxial test data reported in the literature were used to determine endochronic model pa rameters for wheat at 8.1% w.b. (wet basis) moisture content. Comparis ons of predicted stress-strain behavior with the experimental data sho wed that the endochronic model adequately described the characteristic s of stress-strain-dilatancy for wheat en masse. The predictive finite element model was validated against experimental data reported in the literature for static loading conditions. The maximum difference betw een predicted and measured lateral pressures was 10% and the average d ifference 6%.
