The paper reports on a study that deals with the stress-density behavior of bulk forages during compression in a cylindrical die, and with the cohesive strength associated with consolidated forages. A fundamental analysis of the deformation occurring during compression is included, and a theoretical model for the instantaneous density resulting from a given stress input is developed. The parameters are estimated from experiment. Bulk stiffness was found to be sensitive to crop type, and to follow a nearly linear relationship with moisture content. A load constant parameter was introduced and found to be a useful indicator of the additional density likely to occur for increased stress input.
