Original abstract
Fracture surfaces generated under combined bending-torsion fatigue loading in both the low-cycle fatigue and the high-cycle fatigue reagions of specimens made of high-strength low-alloy Cr-Al- Mo steel are analyzed in terms of topographical characteristics. As a main result of the analysis the critical portion of torque beyond which the character of fracture topography significantly changes is estimated to be withi the range of 40-50% of a total loading.
Czech abstract
Lomové povrchy vzorků z vysocepevné nízkolegované Cr-Al-Mo oceli, získané kombinovaným zatěžováním v ohybu-krutu v oblasti nízkocyklové i vysokocyklové únavy, jsou analyzovány z hlediska topografických parametrů. Hlavním výsledkem je stanovení krtického podílu krutové složky namáhání v rozmezí 40-50% nad nímž se výrazně mění charakter lomové topografie .
