Shear Stress in Ansys vs. Hand Calculation"},"content":{"rendered":"<p>Good morning all,<\/p>\n<p><\/p>\n<p>I am trying to compare Ansys results to hand calculations for Shear Stress and Maximum Shear Stress for a simple cantilever beam (10mm x 10mm x 100mm) with a 1N load at the end face. I have modeled the solid beam in SpaceClaim as an extrusion of a rectangle so I am not using the predefined beams built in SpaceClaim.<\/p>\n<p><\/p>\n<p>At the fixed support, I ended up using remote displacement to have the option of deformable behavior on because when using the standard fixed support I get singularity points that mess up the results.<\/p>\n<p><\/p>\n<p>The support and the load has been applied to the faces at each end of the solid beam (normal to the longitudinal axis Y)<\/p>\n<p><\/p>\n<p>The hand calculation for the Shear Stress is just the Load\/Area and for the Maximum Shear Stress is (3\/2)*Load\/Area.&nbsp;<\/p>\n<p><\/p>\n<p>I get the Von Mises Stress spot on but for the Shear Stress and Maximum Shear Stress I get odd results. If you could help me understand what is going on it would be very much appreciated.<\/p>\n<p><\/p>\n<p>Please see pictures below.<\/p>\n<p><\/p>\n<p>Best Regards,<\/p>\n<p><\/p>\n<p>Pablo<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/387faf71-b012-4e15-a4f5-ab9600df8c8e_max-deformation.jpg?width=690&amp;upscale=false\" alt=\"Max Deformation\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/721ef548-ae6e-4888-9303-ab9600dfaee2_max-shear-stress-section-2.jpg?width=690&amp;upscale=false\" alt=\"Max Shear Stress Section 2\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/c29ca4c4-0032-4962-952d-ab9600dfc864_max-shear-stress.jpg?width=690&amp;upscale=false\" alt=\"Max Shear Stress\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/58ff7790-102f-4863-8de5-ab9600dff11b_shear-stress-section-1.jpg?width=690&amp;upscale=false\" alt=\"Shear Stress Section 1\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/41ae7284-9c9e-495b-8832-ab9600e00817_shear-stress-section-2.jpg?width=690&amp;upscale=false\" alt=\"Shear Stress Section 2\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/092c7bae-1914-40f6-85a3-ab9600e01c42_shear-stress.jpg?width=690&amp;upscale=false\" alt=\"Shear Stress\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/8fefca31-5eaa-404e-a20f-ab52013b6b15\/b063f9e0-8fb9-4e03-9bb5-ab9600e02f6f_von-mises.jpg?width=690&amp;upscale=false\" alt=\"Von Mises\"><\/p>\n","protected":false},"template":"","class_list":["post-42522","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_old_topic_id":["14702"],"_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"],"_btv_view_count":["11905"],"_bbp_subscription":["247017"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["42522"],"_bbp_forum_id":["27791"],"_bbp_engagement":["88","200","172737"],"_bbp_voice_count":["3"],"_bbp_reply_count":["6"],"_bbp_last_reply_id":["113279"],"_bbp_last_active_id":["113279"],"_bbp_last_active_time":["2020-05-02 15:54:50"]},"test":"psn83"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/42522","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\/42522\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=42522"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
