"Recent Developments in Textural Fractography of Fatigue Fractures"@en . "Textural fractography consists in relating fatigue crack growth rate (CGR) with the image texture in SEM fractographs. Two improvements were finalized in 2010-2011: 1. Textural analysis based on 3D crack surface representation was proposed and tested on CT specimens made from aluminum alloy. Crack surfaces were documented by SEM images, and four methods of 3D reconstruction. Results based on 3D reconstruction from equidistantly focused optical images almost reached quality of standard analysis from SEM images. 2. A physical explanation of reference features was proposed. A common subset of image textures in fractographs of fatigue fractures, reference texture, is unambiguously linked with the reference crack growth rate. Reference features were found to be closely related to a parameter derived from successive sizes of cyclic plastic zone. In application on CT specimens from aluminum alloy loaded by 3 loading regimes, a maximal discrepancy of reference factors of about 20% was reached." . . "3"^^ . . "Lauschmann, Hynek" . . "1"^^ .
