MATHEMATICAL DESCRIPTION OF RAPE SEEDS’ (BRASSICA NAPUS L.) MIXTURE MECHANICAL BEHAVIOR UNDER COMPRESSION LOADING

This article is concentrated on the utilization of tangent curve equation for description of mechanical behavior of rapeseeds (Brassica napus L.) pressed mixture under compression loading. This experiment was aimed at determining of the general equation describing deformation characteristics of rapeseeds pressed mixtures under compression loading and at verifying of this equation. Pressing vessel with diameter 76 mm was used where different pressing heights were performed for the rapeseeds pressed mixtures. The results from the experiment showed that mechanical behavior of the rapeseeds pressed mixtures under compression loading can be described by the general tangent curve function. From the determined coefficients of determination and also statistical analysis it was shown that fitted tangent curve function described the measured amounts exactly for different pressing heights of the rapeseeds. The determined general equation can be used for description of mechanical behavior of rapeseeds mixture under compression loading
