“…This must be preceded by research of fruit mechanical properties which are related to the parameters describing impact effects. [11][12][13][14][15][16] There is a large number of papers presenting the impact research carried out on the cylindrical samples of fruits and vegetables. [17][18][19][20][21] The question arises whether the tests performed on the samples of different sizes and at various impact velocities can be compared.…”

The influence of cylindrical sizes of samples and velocity of impact on its course and strength parameters for the "Braeburn" variety apples was studied. Three sample lengths of 17, 19, and 21 mm, three diameters of 10, 15, and 20 mm and four impact velocities of 0.25, 0.5, 0.75, and 1 ms-1 were applied. Failure stress and strain, impact energy, absorbed energy as well as tissue stiffness and toughness were determined as dependent variables. The influence of the sample diameter on maximum force response, impact energy, absorbed energy, and tissue stiffness was studied. The other independent variables: Sample length and impact velocity did not show significant influence on the strength parameters of the apple tissue. The shock wave speed in the apple tissue was independent of both sample sizes and impact velocity. Its mean value amounted to 292 ms-1. Under the experimental conditions the mean value of the absorbed energy contribution to the impact energy amounted to 9.9%. The experiment confirmed importance of a critical stress criterion as regards cylindrical samples of apples under impact conditions.
