ABSTRACT

A new formulation for the displacement-only partitioned equations of motion for linear structures presented in Part I is summarized as
𝑴 𝒅̈ = 𝐏𝐝( 𝒇 − 𝑲 𝒅)                                    (1)
Where ( 𝒅̈, 𝒅, 𝒇) the partitioned accelerations, partitioned displacements and partitioned applied forces acting on each partition, (M, K) are block-diagonal partitioned mass and stiffness
matrices, and Pd is the coupling projector.

Part II presents initial applications of the proposed formulation as applied to unconditionally stable explicit-implicit transient analysis, static parallel analysis in an iterative solution mode; reduced-order modeling (component mode synthesis); localized damage identification which can pinpoint damage locations. Part II ends with potential additional applications such as multuphysics modeling and solution methods, optimization and active vibration/noise control, etc.
