Abstract

An incremental finite element formulation was developed to simulate the viscoelastic behavior of soybean and corn kernels during drying. Failure was predicted in a soybean kernel dried at 75°C and a corn kernel dried at 85°C, using von Mises failure criteria and experimentally determined strength properties. Calculated tangential stresses.
