Title : Experiment and analysis of compressive mechanical behavior and creep characteristics for apples

Abstract :

The compressive mechanical behavior and creep behavior of Fuji apple were studied under the same agroecological conditions. The compression test results showed that the order of the factors affecting the damage force, stiffness and deformation energy were loading rate, storage time and compression position. The loading rate and storage time showed an extremely significant effect on damage force and stiffness (P<0.01), which also showed a significant effect on deformation energy (P<0.05). The loading position showed a significant effect on damage force and stiffness (P<0.05). The creep test results showed that the four-element Burgers model had the highest mean fitting degree. The initial elasticity coefficient, delayed elasticity coefficient and viscosity coefficient all showed a downward trend with the increase of storage time, while the delay time showed an upward trend with the increase of storage time. Moreover, the creep parameters showed a significant or an extremely significant correlation relationship.
