Previously, researchers used methods rooted in classical continuum mechanics and numerical differential equations to predict corrosion. Numerical solvers, such as the Finite Element Method or Extended FEM,&nbsp; utilized \u201cmeshing\u201d and \u201cremeshing\u201d to account for boundary displacement. However, these approaches depended on partial differential equations which were poorly suited to model crack propagation. The Peridynamic method substitutes nonlocal operators such as force and displacement integrals for the classical stress and strain partial derivatives. We use the peridynamic corrosion equation (PCE), a simplified model derived from the conservation of linear momentum. We adjust the PCE to account for electrochemical corrosion processes, replacing the physical phenomenon of the \u201cgeneralized degradation function\u201d with the scalar field of the chemical \u201ccorrosion penetration rate.\u201d This enables us to assess the level of corrosion on a material point-by-point basis.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Presentation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Session 1 \u2013 1:30p.m. \u2013 2:45p.m.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Room D \u2013 Sierra 2422&nbsp;<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Curtis Hauck, Trent Ruiz, Sabrina Shenker, Citlalli Villegas, Piolo Miguel Sanchez, Daniel Lopez, Sheradyn Reuf, Patrick McDonough, and Dr. Cynthia Flores\u00a0<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"categories":[20,27,21],"tags":[7],"class_list":["post-287","page","type-page","status-publish","hentry","category-oral","category-room-d","category-session-1","tag-mathematics","post"],"_links":{"self":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/287","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/comments?post=287"}],"version-history":[{"count":3,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/287\/revisions"}],"predecessor-version":[{"id":562,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/pages\/287\/revisions\/562"}],"wp:attachment":[{"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/media?parent=287"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/categories?post=287"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/src.cikeys.com\/2022\/wp-json\/wp\/v2\/tags?post=287"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
