In this paper dynamic damping properties of a nominated flexible structural adhesive have been identified using an extended-direct modal based joint identification method. It has been revealed that damping characteristics of adhesive are correlated to both frequency and mode shape. Young’s and shear moduli increase with frequency but damping on the other hand, decrease. The results showed that ...

Our first goal in this work is to study general and model-independent properties of cyclic cosmologies. The large number studies bouncing cosmologies different scenarios published recently calls for a proper understanding the universal models. We thus review further elaborate common physical geometrical various classes models then discuss how Universe can be treated as dynamic system. two theor...
