The model extends classical AT1\/AT2 formulations with linear, exponential, and hyperbolic softening laws, calibrated through tensile tests on flat 3D-printed PLA specimens. Comparisons with experiments under tensile and compressive loads show accurate reproduction of crack initiation, propagation, and failure mechanisms. The formulation demonstrates strong predictive capability and opens perspectives for applications in coated structures, other complex bio-inspired structures, and nano and micro-scale effects.<\/p>\n<p data-renderer-start-pos=\"1690\">&#8211; N\u00e3o h\u00e1 necessidade de inscri\u00e7\u00e3o;<br \/>\n&#8211; E-mail para contato: <a class=\"_mizu194a _1ah31bk5 _ra3xnqa1 _128m1bk5 _1cvmnqa1 _4davt94y _4bfu1r31 _1hms8stv _ajmmnqa1 _vchhusvi _syaz14q2 _ect41gqc _1a3b1r31 _4fpr8stv _5goinqa1 _f8pj14q2 _9oik1r31 _1bnxglyw _jf4cnqa1 _30l314q2 _1nrm1r31 _c2waglyw _1iohnqa1 _9h8h16c2 _1053w7te _1ienw7te _n0fxw7te _1vhvg3x0\" title=\"mailto:ppgset@eesc.usp.br\" href=\"mailto:ppgset@eesc.usp.br\" data-renderer-mark=\"true\" data-is-router-link=\"false\" data-testid=\"link-with-safety\">ppgset@eesc.usp.br<\/a>;<br \/>\n&#8211; Palestra presencial (n\u00e3o haver\u00e1 transmiss\u00e3o online);<br \/>\n&#8211; Ser\u00e1 emitido certificado de participa\u00e7\u00e3o.<\/p>\n<p>{{<\/p>\n<p>SERVI\u00c7O<br \/>\n<strong>Data do Evento:<\/strong> 14 de novembro, sexta-feira<br \/>\n<strong>Hor\u00e1rio:<\/strong> 14h30 \u00e0s 15h30<br \/>\n<strong>Local:<\/strong> Audit\u00f3rio do Departamento de Engenharia de Estruturas (SET)<\/p>\n<p>}}<\/p>\n<p data-renderer-start-pos=\"1820\">\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>O tema ser\u00e1 abordado pelo Dr. Deison Preve, e o evento ser\u00e1 realizado no dia 14 de novembro.<\/p>\n","protected":false},"author":9,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"inline_featured_image":false,"footnotes":""},"categories":[111,175],"tags":[238,321,396,304],"class_list":["post-54499","post","type-post","status-publish","format-standard","hentry","category-comunicados-alunos","category-eventos","tag-eesc","tag-engenharia","tag-estruturas","tag-usp","entry"],"_links":{"self":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts\/54499","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=54499"}],"version-history":[{"count":10,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts\/54499\/revisions"}],"predecessor-version":[{"id":54540,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=\/wp\/v2\/posts\/54499\/revisions\/54540"}],"wp:attachment":[{"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=54499"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=54499"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/eesc.usp.br\/comunicacao-admin\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=54499"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
