Abstract
A finite element algorithm was developed using an endochronic constitutive model to predict loads in grain storage bins. Triaxial test data reported in the literature were used to determine endochronic model parameters for wheat at 8.1% w.b. (wet basis) moisture content. Comparisons of predicted stress-strain behavior with the experimental data showed that the endochronic model adequately described the characteristics 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 between predicted and measured lateral pressures was 10% and the average difference 6%.
