In this study, tensile tests were carried out on several carbon steels that had been heat-treated using various methods. Their fracture surfaces were observed using scanning laser microscopy. Based on the obtained digital data, an imaginary fracture surface was reconstructed in a three-dimensional (3D) space. Fractal analysis was applied to those 3D surfaces and the Richardson effect was confirmed in the surface irregularity. Finally, it was noted that the geometrical irregularity of the surface is well evaluated by combining the fractal dimension and an additional indices designated as indices of fracture surface nature.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
