Abstract: A theoretical method is employed to study the free vibration characteristics of a finite ring-stiffened elliptic cylindrical shell. Vibration equations of the elliptic cylindrical shell are derived based on Flügge shell ...

Abstract: Stability analysis and risk assessment are key issues in the design and construction of tunnels; however, these assessments are often hard to conduct accurately because of the complexity of tunnel engineering. In order to ...

Abstract: The ideal acoustic black hole (ABH) can achieve wave gathering and zero reflection of elastic waves. In practice, ABHs have to be truncated, limiting their application in lower frequency range. Aiming at improving the ABH ...

Abstract: This study aims to establish an appropriate method to calculate the bearing deformation of large-diameter bored piles in alluvial deposits with soils characterized mainly by medium-dense to dense silt, fine sand, and plastic ...
