The simulation of feeding systems, handling and classifications of shafts of canes of sugar require of a behavior model that predicts which it is the maximum effort that you can apply on a shaft without it breaks the internal structure of the vegetable, achieving this way a bigger productive capacity. For this simulation process it becomes necessary to obtain a mathematical model that describes the phenomenon. The geometric pattern is obtained starting from the morphological analysis of the cane of sugar and the application of the structural theory, being reached the conclusion that a polygonal structural model of 12 bars if they are imposed to the properties of the material the multi-elasticity several load situations they can be studied. The determination of the load that causes the maximum effort without it breaks the internal structure of the shaft loaded traversely it was obtained through laboratory rehearsals where load, displacement was controlled and it plows of the cellular walls. The confirmation of the pattern was carried out comparing data obtained in a simulation with those of a laboratory rehearsal being obtained the mechanical behavior of the bars of the geometric pattern able to reproduce the physical behavior of the varieties analyzed with a level of trust of 95%.
