To represent the damage of the tissue while preserving the initial mass, I modeled the part that comes into contact with the blade using the SPG section (KERNEL = 1; ITB = 3; ISC = 1). I have tried to include material failure both through the SPG section using the IDAM variable, and through the *MAT_ADD_EROSION keyword.&lt;\/p&gt;&lt;p&gt;However, the simulation results do not seem sensitive to the values I input for material failure: the blade penetrates deforming and cutting the SPG part even when I disable material failure.&lt;\/p&gt;&lt;p&gt;What could be the explanation for this behavior?&lt;\/p&gt;&lt;p&gt;Thank you very much in advance.&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-387683","topic","type-topic","status-publish","hentry","topic-tag-FailureModel-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["74325","13468"],"_bbp_author_ip":["93.44.200.162"],"_btv_view_count":["239"],"_bbp_topic_status":["unanswered"],"_bbp_topic_id":["387683"],"_bbp_forum_id":["27814"],"_bbp_engagement":["13468","74325"],"_bbp_voice_count":["2"],"_bbp_reply_count":["2"],"_bbp_last_reply_id":["388329"],"_bbp_last_active_id":["388329"],"_bbp_last_active_time":["2024-10-07 07:14:15"]},"test":"lantoniniparametricdesign-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/387683","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\/387683\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=387683"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
