Comparison of Fatigue Criteria for Combined Bending-torsion Loading of Nitrided and Virgin Specimens
Result description
This work deals with fatigue life of plasma-nitrided and virgin specimens made of the low-alloy high strength steel. Specimens were subjected to an in-phase combined bending-torsion loading. The plasma-nitride specimens exhibited a significantly improvedfatigue resistance. The criterion proposed by McDiarmid was found to be the most precise in the fatigue life prediction for virgin specimens. On the other hand, the Matake criterion was the most successful for nitrided specimens.

Srovnání únavových kritérií pro kombinaci ohyb-krut na nitridovaných a hladkých vzorcích
Czech description
Práce analyzuje únavovou životnost plazmaticky nitridovaných a hladkých vzorků z vysocepevné oceli. Vzorky byly podrobeny soufázovým zatěžováním v kombinaci ohyb-krut. Nitridované vzorky vykázaly podstané zvýšení životnosti. Jako nejlepší se jevilo McDiarmidovo kritérium pro hladké vzorky, zatímco Matakovo kritérium nejlépe popisovalo životnost nitridovaných vzorků.
