Abstract:A nonlinear viscous-elastic-plasticity constitutive model for rapeseed and rapeseed kernel was developed on the basis of the theological test. The parameter inverse of the constitutive model was carried out using the improved simulation annealing. The maximum relative deviation between the experimental and predicted values of the strain is below 8.8M, which indicates that the nonlinear viscous-elastic-plasticity constitutive model can simulate theological behaviors of rapeseed and rapeseed kernel well.
Keywords:Rapeseed  Rapeseed kernel  Nonlinear  Viscous-elastic-plasticity  Constitutive model
