In this paper, a metal\/composite L-joint with groove structure was designed, and seven groups with different bonding lengths were fabricated using the VARI (Vacuum Assisted Resin Infusion) process to study the effect of different bonding lengths on the performance of the joint. In the simulation analysis of the metal\/composite L-joint, the stiffness equivalence method was adopted, and the groove structure was equivalent to a 0-thickness element layer. The applicability of the simulation method was verified by comparing the ultimate load, displacement and failure mode of the test and simulation. Furthermore, the simulation method was used to simulate more compression experiments of metal\/composite L-joints with different bonding lengths, and prediction diagrams of failure displacement and failure mode were produced. According to the prediction map, when the bonding length is 100.00 mm, the metal\/composite L-joint has better compressive properties.<\/jats:p>","DOI":"10.3390\/polym14051051","type":"journal-article","created":{"date-parts":[[2022,3,6]],"date-time":"2022-03-06T20:40:02Z","timestamp":1646599202000},"page":"1051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Failure-Mode Shift of Metal\/Composite L-Joint with Grooved Structure under Compressive Load"],"prefix":"10.3390","volume":"14","author":[{"given":"Zhenhang","family":"Kang","sequence":"first","affiliation":[{"name":"Key Laboratory of Advanced Ship Materials and Mechanics, College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhu","family":"Liu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Ship Materials and Mechanics, College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongpeng","family":"Lei","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Ship Materials and Mechanics, College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7798-8032","authenticated-orcid":false,"given":"Jifeng","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Advanced Ship Materials and Mechanics, College of Aerospace and Civil Engineering, Harbin Engineering University, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,6]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"753","DOI":"10.1002\/mawe.201600747","article-title":"Experimental investigations of the environmental effects on stability and integrity of composite sandwich t-joints: Experimentelle untersuchung des umwelteinflusses auf die belastbarkeit von t-st\u00f6\u00dfen in sandwich-platten","volume":"48","author":"Khosravani","year":"2017","journal-title":"Mater.
