Title : Change of surface pressures of apples in the creep test
Key words : surface pressures, apple, compression, time factor, creep
Summary :

The results of the measurements of the surface pressures including the time factor in the test of radial compression between flat panels with the use of the testing machine Instron 5566 were presented. Contour layers and distribution of the surface pressures in different stages of creep test were determined. It was proved that the average values of the surface pressures are subject to minimum changes during the whole test. Distribution of pressures on the surface of apple contact with the loading element undergoes a significant change. In the initial stage of the test, distribution of the surface pressures has a typical shape for contact issues - maximum values are in the central sphere. Value of the surface pressures in the central sphere decreases with time at the simultaneous increase in the border sphere. The contact surface with the maximum surface pressures clearly increases.
