The experiments were carried out using the Kolsky (or split-Hopkinson pressure bar) method, and its modifications in the strain rate range from 400 to 2000 s\u22121. The rate dependences of ultimate stresses and fracture energy in tension and compression are obtained. Based on experimental data, the identification of the dynamic component of two models from the LS-DYNA computational complex was carried out: *MAT_CONCRETE_DAMAGE and *MAT_CSCM. The results of a comparative analysis of the identified models based on single-element modeling and comparison with experimental data are presented. It is shown that the obtained experimental strain rate dependences of the fracture characteristics can significantly improve the predictive ability of the model compared to the default parameter set. Information about the rate dependence of the fracture energy in *MAT_CSCM model makes it possible to more realistically simulate the behavior of the material beyond the ultimate stress.<\/jats:p>","DOI":"10.3390\/ma16062259","type":"journal-article","created":{"date-parts":[[2023,3,13]],"date-time":"2023-03-13T03:03:57Z","timestamp":1678676637000},"page":"2259","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Identification of Dynamic Behavior Models of Concrete B22.5"],"prefix":"10.3390","volume":"16","author":[{"given":"Anatoly M.","family":"Bragov","sequence":"first","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrey K.","family":"Lomunov","sequence":"additional","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikhail E.","family":"Gonov","sequence":"additional","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandr Yu.","family":"Konstantinov","sequence":"additional","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leonid A.","family":"Igumnov","sequence":"additional","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8128-3262","authenticated-orcid":false,"given":"Victor A.","family":"Eremeyev","sequence":"additional","affiliation":[{"name":"Research Institute of Mechanics, National Research Lobachevsky State University of Nizhny Novgorod, 603022 Nizhny Novgorod, Russia"},{"name":"Department of Civil and Environmental Engineering and Architecture (DICAAR), University of Cagliari, Via Marengo 2, 09123 Cagliari, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"676","DOI":"10.1088\/0370-1301\/62\/11\/302","article-title":"An investigation of the mechanical properties of materials at very high rates of loading","volume":"62","author":"Kolsky","year":"1949","journal-title":"Proc.
