The basic characteristics of the material at the temperatures of 100, 200 and 300 \u00b0C were determined, such as the Young\u2019s modulus E, yield point \u03c3y, ultimate tensile strength \u03c3c and parameters K and n of the Ramberg\u2013Osgood equation. Creep tests were performed for several different levels of nominal axial stress (load) at each temperature. It was observed that in the process of creep to failure at 200 and 300 \u00b0C, as the stress decreases, the creep time increases and, at the same time, the strain at rupture increases. However, such a regularity is maintained until a certain transition stress value \u03c3t is reached. Reducing the stress below this value results in a decreased value of the strain at rupture. A simple model of creep damage accumulation was proposed for the stress range above the transient value. In this model, the increase in the isotropic damage state variable was made dependent on the value of axial stress and the increase in plastic axial strain. Using the results of experimental creep-rupture tests and the failure condition, the parameters of the proposed model were determined. The surface of fractures obtained in the creep tests with the use of SEM technology was also analyzed.<\/jats:p>","DOI":"10.3390\/ma14020404","type":"journal-article","created":{"date-parts":[[2021,1,15]],"date-time":"2021-01-15T12:44:05Z","timestamp":1610714645000},"page":"404","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Experimental Investigation and Modeling of Damage Accumulation of EN-AW 2024 Aluminum Alloy under Creep Condition at Elevated Temperature"],"prefix":"10.3390","volume":"14","author":[{"given":"Adam","family":"Tomczyk","sequence":"first","affiliation":[{"name":"Faculty of Mechanical Engineering, Bia\u0142ystok University of Technology, Wiejska 45C Str., 15-351 Bia\u0142ystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrzej","family":"Seweryn","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, Bia\u0142ystok University of Technology, Wiejska 45C Str., 15-351 Bia\u0142ystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,15]]},"reference":[{"key":"ref_1","unstructured":"Norton, F.H.
