Abstract: In some geometrically nonlinear problems, the effects of external loads are altered significantly by the deformations of structures themselves. In finite element analysis, the assumed displacement method is often used to ...

Abstract: In this paper, an effective and new one-dimensional theory for the analysis of strip surface acoustic waveguides is presented. Compared with the known methods, a prominent advantage of this ...

Abstract: Operational modal analysis (OMA) has been widely used for large structures. However, measured signals are inevitably contaminated with noise and may not be clean enough for identifying the modal parameters with proper ...

Abstract: The torsional vibration calculations of the complicated multi-branched system with rigid connection and flexible connections made up of elastic-coupling parts are very difficult to perform using ...

Abstract: Flood disasters have plagued developing countries and impeded sustainable city development as a result of global climate change and economic development. Chaotic urban flooding prevention system management is the current ...
