I have to do FEM anlalysis of aircraft frame. It consists of frame, rivets , skin panel.<\/p>\n

It is only anlysis of inlet which means only loads that are in the inlet due to airflow will be considered. Skin on inlet portion is connected to frame using rivets. I have to find which rivets are in critical condition. <\/p>\n

Following are the questions:<\/p>\n

    \n
  1. What should be the boundary conditions. Should i use fixed support,remote displacement or displacement on aircraft frame outside.<\/li>\n
  2. What should be the boudary condition on skin .eg I should apply elastic support on its sides since in reality it is constrained from side skin as well.<\/li>\n
  3. What should be the contacts for rivets. (rivet head to skin, Rivet tail to frame , skin to frame , Rivet shanks to holes in skin and frame.<\/li>\n
  4. Right now i am considering two loadings one is the Total pressure applied normally to aircraft skin. Wall shear stress in the direction of airflow to the skin. Is there any other boundary condition to consider.Thanks in advance.<\/li>\n<\/ol>\n","protected":false},"template":"","class_list":["post-292818","topic","type-topic","status-closed","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_subscription":["288740","200","50680"],"_bbp_author_ip":["23.33.28.199"]," _bbp_last_reply_id":["0"]," _bbp_likes_count":["0"],"_btv_view_count":["328"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["292818"],"_bbp_forum_id":["27791"],"_bbp_engagement":["200","50680","288740"],"_bbp_voice_count":["3"],"_bbp_reply_count":["4"],"_bbp_last_reply_id":["293215"],"_bbp_last_active_id":["293215"],"_bbp_last_active_time":["2023-07-15 12:10:58"]},"test":"abdullah-shah5267gmail-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/292818","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\/292818\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=292818"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
