Statistical analysis of the surface relief parameters of single crystals in constrained tension with the MATLAB program in the Desktop Grid distributed computing environment
Using a subprogram developed for the MATLAB program package, we statistically processed the elements of the surface relief of Al single crystal foils rigidly fixed with a polycrystalline Al alloy specimen under static tension. For the processing, individual frames of the video film shot during the deformation were used. The single crystal relief was statistically processed after image filtering and separation of relief elements from the background with a certain threshold. Successive development of the relief consists in the transition from equiaxial and small-area relief elements oriented at 40°-45° about the loading axis to extended and enlarged elements oriented at 40°-85°.
