How do I properly model a series stack of Belleville washers to simulate the pre-load properly? I need to ensure the compression forces correctly transfer through the stack to the straps. The washers are meant to provide damping, so I need to accurately represent that behavior.&lt;\/p&gt;&lt;p&gt;Thank you!&lt;\/p&gt;&lt;p&gt;&nbsp;&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/04\/02-04-2026-1775163574-mceclip0.png\" \/>&lt;\/p&gt;&lt;p&gt;<img decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2026\/04\/02-04-2026-1775163762-mceclip1.png\" \/>&lt;\/p&gt;<\/p>\n","protected":false},"template":"","class_list":["post-455695","topic","type-topic","status-publish","hentry"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_bbp_forum_id":["27791"],"_bbp_topic_id":["455695"],"_bbp_subscription":["671765","240"],"_bbp_author_ip":["130.76.187.33"],"_bbp_last_reply_id":["455746"],"_bbp_last_active_id":["455746"],"_bbp_last_active_time":["2026-04-03 16:08:40"],"_bbp_reply_count":["1"],"_bbp_reply_count_hidden":["0"],"_bbp_voice_count":["2"],"_bbp_engagement":["671765","240"],"_btv_view_count":["12"],"_bbp_topic_status":["unanswered"]},"test":"thamer-husseinboeing-com"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/455695","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\/455695\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=455695"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
