Local-Global Interactions in the Transient Response of Lattice-Truss Plates.
Abstract
The transient response of lattice truss plates is studied with emphasis on how the individual lattice members dynamic characteristics influence with transient response characteristics. When the lattic members are modeled as bars, the transient responses are dominated by the low frequency components that correspond to the continuum thick plate case. However, when the lattic members are modeled as slender beams to be more realistic, the dynamic characteristics of the individual lattice members significantly influence the global transient response. The level of influence increases as the member slenderness ratio increases. The results underscore the importance of local high wave member modes that must be treated satisfactorily both in passive and active control of large lattice truss space structures.
