Abstract
Two component mode sets are identified as satisfying the basic requirements for inter-component compatibility, high convergence rate, linear independence and completeness. From these, fixed-interface and free-interface CMS formulations specific to the component mode sets are derived in a form applicable to linear, undamped, discrete systems of an arbitrarily complex geometry. First- and second-order mass approximations are used in two variations of the free-interface formulation.
