Original abstract

The paper deals with quantitative analysis of morphology of the fracture surfaces generated under pure torsion, pure bending, and mixed bending-torsion loading. Characteristics of roughness and fractality are studied in dependence on loading conditions, profile orientation and distance from the specimen surface, respectively. Moreover, the mismatch between matching profiles is analysed for all investigated specimens. As expected, the surface roughness increases with increasing distance from the specimen surface. A strong increase in the mismatch with increasing torsion component can be considered to be the most important result of the analysis.

Czech abstract

Článek se týká kvantitativní analýzy morfologie lomových ploch vytvořených při čistém krutu, čistém ohybu a kombinaci ohyb-krut. Jsou studovány charakteristiky drsnosti a fraktality v závislosti na zatížení, orientaci a vzdálenosti od povrchu vzorku. Navíc je analyzován rozdíl mezi vzájemně si odpovídajícími profily pro všechny vyšetřované vzorky. Podle očekávání se povrchová drsnost zvyšuje s rostoucí vzdáleností od povrchu vzorku. Za významný výsledek analýzy lze považovat výrazně se zvyšující rozdílnost profilů s růstem torzní složky.
