We associate this inequality with a gap function, together with two additional problems: a nonlinear equation and a minimization problem. Then, we prove that solving these problems is equivalent to solving the original history-dependent variational inequality. Next, we state and prove a convergence criterion, i.e., we provide necessary and sufficient conditions which guarantee the convergence of a sequence of functions to the solution of the considered inequality. Based on the equivalence above, we deduce various consequences that present some interest on their own, and, moreover, we obtain convergence results for the two additional problems considered. Finally, we apply our abstract results to the study of an inequality problem in solid mechanics. It concerns the study of a viscoelastic constitutive law with long memory and unilateral constraints, for which we deduce a convergence result and provide the corresponding mechanical interpretations.<\/jats:p>","DOI":"10.3390\/axioms13050316","type":"journal-article","created":{"date-parts":[[2024,5,13]],"date-time":"2024-05-13T11:18:17Z","timestamp":1715599097000},"page":"316","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Convergence Results for History-Dependent Variational Inequalities"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6110-1433","authenticated-orcid":false,"given":"Mircea","family":"Sofonea","sequence":"first","affiliation":[{"name":"Laboratoire de Math\u00e9matiques et Physique, University of Perpignan Via Domitia, 52 Avenue Paul Alduy, 66860 Perpignan, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2813-0419","authenticated-orcid":false,"given":"Domingo A.","family":"Tarzia","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1tica, FCE, Universidad Austral, Paraguay 1950, Rosario S2000FZF, Argentina"},{"name":"CONICET, Rosario S2000EZP, Argentina"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"115","DOI":"10.5802\/aif.280","article-title":"Equations et in\u00e9quations non lin\u00e9aires dans les espaces vectoriels en dualit\u00e9","volume":"18","year":"1968","journal-title":"Ann.
