I am trying to analyze the effect of a blood vessel on a stent.&lt;\/p&gt;<\/p>\n<ol>\n<li>I assigned the material properties of the vessel to the vessel. For the stent, as seen in the table, I assigned five different materials sequentially.<\/li>\n<li>I chose the bond type between the vessel and the stent as bonded.<\/li>\n<li>The mesh settings are as shown in the visual.<\/li>\n<li>I constrained both ends of the vessel and applied a pressure of 1200 mmHg to its inner surface.<\/li>\n<\/ol>\n<p>&lt;p&gt;When I ran the simulation, the material with the lowest safety factor among the five materials turned out to be Nitinol. It seems very incorrect to me that Nitinol would have such a low value. I used the materials from ANSYS&#8217;s own library and did not make any modifications. What do you think the issue might be here?<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/22-12-2024-1734896204-mceclip0.png\" \/><img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/12\/22-12-2024-1734896204-mceclip1.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-398219","topic","type-topic","status-publish","hentry","topic-tag-2dmaterialsandmetals-1","topic-tag-ansysworkbench-ansys-staticstructural","topic-tag-mechanicalworkbench-1","topic-tag-add-material","topic-tag-nitinol","topic-tag-safety-factor","topic-tag-shape-memory-alloy","topic-tag-workbench"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["398219"],"_bbp_subscription":["135066","440006"],"_bbp_author_ip":["2a02:e0:9c14:7800:b5a4:4b52:b436:ea7a"],"_bbp_last_reply_id":["398260"],"_bbp_last_active_id":["398260"],"_bbp_last_active_time":["2024-12-23 08:49:56"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["135066","440006"],"_btv_view_count":["172"],"_bbp_topic_status":["unanswered"]},"test":"ffatihkaraoglugmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398219","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/398219\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=398219"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
