Loss　of　clamping　force　due　to　elastic　interaction　is　unpredictable　and　nonnegligible　with　the　typical　non-linear　characteristics　of　gasketed　joints.　It　is　hard　to　weaken　or　eliminate　elastic　interaction　by　suitable　joint　dimensions.　An　analytical　model　of　elastic　interaction　with　dimensional　representation　is　constructed　using　gasket　deformation　as　a　bridge.　The　influence　of　multi-dimensional　dimensions　on　clamping　force　losses,　such　as　bolt　spacing,　joint　width　and　thickness,　was　explored　by　non-linear　finite　element　analysis　for　a　typical　sandwich　structure　with　two-bolt　gasketed　joints.　Dimensional　singularities　without　elastic　interaction　are　validated　and　their　approximate　range　is　determined.　It　is　clarified　that　initial　clamping　force　or　joint　material　can　cause　dimensional　singularity　movement.　This　paper　provides　a　theoretical　basis　for　solving　the　problem　of　clamping　force　losses　and　inhomogeneities　effected　by　elastic　interactions　in　engineering.
