Energy Balance of Subsystem Local Parametric Modification Process

In the paper the local modification process was considered, which results in the change in the mass, stiffness, damping matrix elements as well as in the energy balance. Energetic analysis was carried out in physical and modal coordinates taking into account nonzero energy dissipated or supplied in the process of local parametric modification. The analysis makes it possible to describe energetic parameters of any subsystem before and after such modifications.
