Synthesis and control of generalized dynamically substructured systems [PDF]

open access: yesProceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 2008
The experimental technique for testing engineering systems via the method of dynamic substructuring is receiving significant global interest, for example in the fields of large-scale structural, aerospace, and automotive system testing. Dynamically substructured systems (DSSs) enable full-size, critical components of a complete system to be physically ...

Frequency Domain Structural Synthesis Applied to Quasi-Static Crack Growth Modeling

open access: yesShock and Vibration, 2009
Quasi-static crack growth in a composite beam was modeled using the structural synthesis technique along with a finite element model. The considered crack was an interface crack in the shear mode (i.e. mode II), which occurs frequently in the scarf joint
