The rheological model is presented as a single-degree-of-freedom system, for the two cases: a symmetrical excitation (perfect elastoplasticity); and an asymmetry in the compression field. The energizing assessment is essentially established from the dissipated energy map during the oscillations, according to the structural parameters of the model (equivalent angular frequency, damping, parameter of the asymmetric excitation force\u2026). A dissipation of the limit cycle energy observed for the alternating plasticity behavioural area, which is controlled by the bifurcation boundary.<\/p>\n<p style=\"text-align: justify;\"><strong><em>Keywords:<\/em><\/strong> Perfect Damped Elastoplastic Oscillator, Rheological model, Dissipated energy, Limit cycle, Alternating plasticity, Bifurcation boundary.<\/p>\n<p><span style=\"color: #444444; text-align: justify;\">e<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Num\u00e9ro de la revue:\u00a036 Auteurs:\u00a0Mahmoud Chenia1, 2, Abdelaziz Hammouda2, Abdel Madjid Hacene Chaouch2 \u00a0 \u00a0&amp;\u00a0 No\u00ebl Challamel3 1Laboratory\u00a0 of\u00a0 Civil Engineering\u00a0 (LGC), Department of Civil Engineering, Badji Mokhtar-Annaba University, PO Box 12, 23000, Annaba, Algeria. 2Laboratory of\u00a0 Materials, G\u00e9o-Materials, and &hellip; <a href=\"https:\/\/synthese.univ-annaba.dz\/?p=7713\">Lire la suite <span class=\"meta-nav\">&raquo;<\/span><\/a><\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1248],"tags":[1271,1272,1269,1270,1267,1268],"class_list":["post-7713","post","type-post","status-publish","format-standard","hentry","category-synthese-n-36","tag-alternating-plasticity","tag-bifurcation-boundary","tag-dissipated-energy","tag-limit-cycle","tag-perfect-damped-elastoplastic-oscillator","tag-rheological-model"],"_links":{"self":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/7713","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=7713"}],"version-history":[{"count":5,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/7713\/revisions"}],"predecessor-version":[{"id":7767,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=\/wp\/v2\/posts\/7713\/revisions\/7767"}],"wp:attachment":[{"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=7713"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=7713"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/synthese.univ-annaba.dz\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=7713"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
