Abstract: | An automated method for analyzing the shape and size of dimples of ductile tearing formed
during static and impact fracture of titanium alloys VT23 and VT23M is proposed. The method is
based on the analysis of the image topology. The method contains the operations of smoothing the
initial fractographic image; its convolution with a filter to identify the topological ridges; thresholding
with subsequent skeletonization to identify boundaries between dimples; clustering to isolate
the connected areas that represent the sought objects—dimples. For each dimple, the following
quantitative characteristics were calculated: area, coefficient of roundness and visual depth in units of
image intensity. The surface of ductile tearing was studied by analyzing the peculiarities of parameter
distribution of the found dimples. The proposed method is applied to fractograms of fracture surfaces
of titanium alloys VT23 and VT23M. |
