AA2050-T84 is established as a low-density aluminum alloy with improved Young\u2019s modulus, less anisotropy, and temperature-dependent mechanical properties. During flights, loading rate and temperature variation in aircraft engine subsequent parts are commonly observed. The present work focuses on the effect of loading rate and temperature on tensile and fracture properties of the 50 mm thick (2-inch) AA2050-T84 alloy plate. Quasi-static strain rates of 0.01, 0.1, and 1 s\u22121 at \u221220 \u00b0C, 24 \u00b0C and 200 \u00b0C are considered. Tensile test results revealed the sensitivity of mechanical properties towards strain rate variations for considered temperatures. The key tensile properties, yield, and ultimate tensile stresses were positive strain rate dependent. However, Young\u2019s modulus and elongation showed negative strain rate dependency. Experimental fracture toughness tests exhibited the lower Plane Strain Fracture Toughness (KIC) at \u221220 \u00b0C compared to 24 \u00b0C. Elastic numerical fracture analysis revealed that the crack driving and constraint parameters are positive strain rate dependent and maximum at \u221220 \u00b0C, if plotted and analyzed over the stress ratio. The current results concerning strain rates and temperatures will help in understanding the performance-related issues of AA2050-T84 alloy reported in aircraft applications.<\/jats:p>","DOI":"10.3390\/ma15041590","type":"journal-article","created":{"date-parts":[[2022,2,21]],"date-time":"2022-02-21T08:22:19Z","timestamp":1645431739000},"page":"1590","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Effect of Strain Rate and Temperature on Tensile and Fracture Performance of AA2050-T84 Alloy"],"prefix":"10.3390","volume":"15","author":[{"given":"Nagaraj","family":"Ekabote","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, KLE Technological University, Hubballi 580031, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9402-0189","authenticated-orcid":false,"given":"Krishnaraja G.","family":"Kodancha","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, KLE Technological University, Hubballi 580031, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9242-7591","authenticated-orcid":false,"given":"T.
