I took a test data from the book and try to solve it with ansys workbench. I have modeled the half specimen due to symmetry but haven&#8217;t use the symmetry option from DM. I am facing some problems with the model first it does not show necking at the end of specimen but somewhere in the middle of half specimen.&nbsp;<\/p>\n<p><\/p>\n<p>Any Suggestions how to get the real behavior. The test data i used i below in the image. I have used the Raw true stresses and True plastic strains for multi-linear theory taking first point in table as Yield stress at plastic strain 0.&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/6c09935e-141f-4e2d-aeb7-a97100f5b9b5\/593e5e98-8031-4e64-af3d-a99900a9728c_question-data.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>I am attaching the workbench file.<\/p>\n<p><\/p>\n<p>Many Thanks<\/p>\n","protected":false},"template":"","class_list":["post-31519","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["3691"],"_bbp_old_topic_author_name_id":["Anonymous"],"_bbp_old_is_topic_anonymous_id":["false"],"_bbp_old_closed_status_id":["publish"],"_bbp_author_ip":[null],"_bbp_old_sticky_status_id":["normal"],"_bbp_likes_count":["0","0","0","0","0"],"_btv_view_count":["1202"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["31519"],"_bbp_forum_id":["27791"],"_bbp_engagement":["240","897","159276"],"_bbp_voice_count":["3"],"_bbp_reply_count":["22"],"_bbp_last_reply_id":["69902"],"_bbp_last_active_id":["69902"],"_bbp_last_active_time":["2018-11-20 13:20:04"]},"test":"abdul-malik"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/31519","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\/31519\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=31519"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
