Finite Element and Applied Models of the Stem with Spike Deformation

This article examines the static and dynamic deformation of stem an ear wheat individual grain. The purpose is to determine factors influence on isolate Two stages grain ripening are considered: in early stage, attached spike by stem; second, there no stem, scales. fluctuations considered within Euler–Bernoulli bar theory. developed model divides study dynamics into two stages. first stage studies plant as a whole, while second moving system associated with bending vertical fluctuation forms. uses mechanical characteristics elastic bonds bodies, which determined spring stiffness, moduli, etc. results show that forms fluctuation, frequency much higher than ones. presents natural frequencies at full ripeness phases maturation, point it released from ear.
