Abstract: Phononic crystals make the realization of complete acoustic band gaps possible, which suggests many applications such as vibration isolation, noise suppression, acoustic barriers, filters, wave guides, and transducers. In ...

Abstract: Long-span, single-layer spatial grid structures are widely used in public buildings. The progressive collapse of such structures could cause great losses of property and human life. To accurately capture the performance ...

Abstract: enerally, the results of data assimilation are not well balanced dynamically due to errors in background, observations, or the model itself. So, initialization methods have been introduced to remove spurious gravity waves ...

Abstract: A dynamic experiment of progressive collapse constitutes the basis of a collapse-resistant analysis. To achieve broad applicability and avoid superfluous influencing factors, two representative substructures extracted from ...
