The proposed strain criterion was successfully verified by fatigue tests in cyclic bending with torsion of specimens made of 2017A-T4 and 6082-T6 aluminum alloy. The scatter of test results for cyclic bending and the combination of cyclic bending and torsion is included in the scatter of tests for the cyclic torsion of the analyzed materials. Fracture surfaces for respective bending and torsion in the 6082-T6 aluminum test with strain control showed that, in the case of bending, cracks can be observed that develop from the surface of the specimen towards the bending plane. They are inclined from the fatigue crack at an angle of 45\u00b0 in relation to the crack surface and the remaining cracks come from the static fracture. In the case of torsion, however, a conical fracture at 45\u00b0 and a static torsion zone can be observed.<\/jats:p>","DOI":"10.3390\/ma13214850","type":"journal-article","created":{"date-parts":[[2020,10,29]],"date-time":"2020-10-29T21:21:00Z","timestamp":1604006460000},"page":"4850","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Fatigue Life of Aluminum Alloys Based on Shear and Hydrostatic Strain"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2815-3311","authenticated-orcid":false,"given":"Tadeusz","family":"\u0141agoda","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Opole University of Technology, 45-758 Opole, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4442-7287","authenticated-orcid":false,"given":"Karolina","family":"G\u0142owacka","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Opole University of Technology, 45-758 Opole, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7316-1858","authenticated-orcid":false,"given":"Andrzej","family":"Kurek","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Opole University of Technology, 45-758 Opole, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1007\/s11003-011-9401-x","article-title":"Comparison of the fatigue characteristics for some selected structural materials under bending and torsion","volume":"47","author":"Kurek","year":"2011","journal-title":"Mater.
