Original abstract

The aim of this paper is to study fatigue behaviour of 7075 aluminium alloy at room temperature for both important directions (longitudinal as well as transversal) with respect to the direction of forming. Smooth test bars were subjected to symmetrical push-pull loading at stresses which cover the whole range of lifetime from UTS to permanent fatigue limit. The results are presented above all as S-N curves fitted using suitable regression functions which lead to precise and reliable determination of fatigue limits.

Cílem této práce je stanovení cyklické deformační odezvy a Wöhlerovy křivky na hladkých zkušebních tělesech slitiny 7075 T6 při symetrickém namáhání tah-tlak za normální teploty ve směru tváření (směr L) a dále pak stanovení Wöhlerovy křivky pro celou oblast životnosti (0,5 až 108 cyklů) u studované slitiny, proložení experimentálně naměřenými daty vhodnou regresní funkci a stanovení meze únavy C.
