Abstract

This study, it is aimed to determine some mechanic features ( breaking characteristics) for three different kinds of walnut (Yalova-3, Kaman, and Sebin) at the same loading rate, at three different moisture content, and three different axes. The data of this study are obtained by loading these kinds statically at a loading rate of 43,4 mm/min., and at the moisture content levels of %8, %13, and %18, and on x-x (thickness), y-y (width), and z-z (length) axes. Besides, some physical characteristics such as dimensions, geometrical average diameters, and sphericity of the walnut kinds are determined. At the end of the research, it is determined that as the moisture content level increases, there is a decrease in the power required for breaking, and contrarily there is an increase in the energy value required for displacement and breaking. The results obtained are in a supporting way to the previous studies carried out.
