I am interested in simulating a tensile test to match experimental data. After a bit of research in the literature, I understood that the community uses an anisotropic Hyperelastic material model for these kinds of problems. I went to MCalibration and calibrated a material model based on the experimental data in the Warp and Weft directions and uploaded the material card in Ansys. I am using shell elements as the thickness of the layer is 0.36mm and with large deflection set to on.&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>I ran a transient simulation for a tensile test on a dogbone. The simulation failed to converge. I am attaching some of the settings I used. I tried applying a displacement BC and a velocity BC but it did not make any difference in the convergence. I tried to refine the mesh, I tried to reduce the time step, no success. I tried to simulate the problem with a normal hyperelastic (Ogden) material model from Ansys library, still I am failing to converge.<\/p>\n<p>I am attaching some photos that would help clarify the issues.<\/p>\n<p>&nbsp;<\/p>\n<p>Could someone please guide me on what to do or what might be the problem?<\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/26-10-2023-1698314949-AnisotropicHyperExp1.png\" alt=\"\"><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/26-10-2023-1698314997-AnisotropicHyperExp2.png\" alt=\"\"><\/p>\n<p><img decoding=\"async\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/26-10-2023-1698315024-AnisotropicHyperExp3.png\" alt=\"\"> &nbsp; <img decoding=\"async\" title=\"Material behaviour (experiment)\" src=\"\/forum\/wp-content\/uploads\/sites\/2\/2023\/10\/26-10-2023-1698315113-AnisotropicHyperExp4.png\" alt=\"\"><\/p>\n","protected":false},"template":"","class_list":["post-313464","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["37097","240"],"_bbp_author_ip":["96.7.218.223"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["1645"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["313464"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","37097"],"_bbp_voice_count":["2"],"_bbp_reply_count":["10"],"_bbp_last_reply_id":["314622"],"_bbp_last_active_id":["314622"],"_bbp_last_active_time":["2023-11-02 18:26:18"]},"test":"karim-el-ghamrawyswansea-ac-uk"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/313464","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\/313464\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=313464"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
