Field-consistent higher-order free-interface component mode synthesis

A new free-interface component mode synthesizing technique based on the notion of higher-order eld consistency is proposed. The present technique employs higher-order residual attachment modes in addition to kept normal modes while consistency in matching eld variables at the substructure interface is maintained. The present eld-consistency approach does not increase the size of the synthesized system even if higher-order residual attachment modes are included. Higher-order analyses greatly improves solution accuracy while the nal system size always remains the same as the size of the kept normal modes regardless of the order of residual attachment modes. A general procedure of deriving higher-order residual attachment modes is rst described and then a new eld-consistent higher-order synthesis technique is presented
