... and plastic strain in the soil at the ultimate limit state are presented to reveal the mechanism of wings for enhancing the lateral bearing capacity of monopiles. The effects of the aspect ratio and the number of wings on the bearing capacity of the monopile are further examined under the premise of the same...

... Abstract Detection of free surface waves signature induced by submarine in the stratified environment has been a canonical question. In this paper, we investigate the main body aspect ratio of a generic submarine effect on the free surface waves using RANS simulation. The slenderness ratios L...

Recently, systematic Saturation Analysis (SA) for pulse-loaded beam/plates has been conducted by Prof. Zhu's group: saturated equivalent method for linealy decaying pulse (Zhu and Bai et al., 2017), the effects of the aspect ratio and the boundary condition...

... in vertical direction are about 70% or so, larger than that in horizontal direction. With an increase in aspect ratio, the ratio of inertia coefficient in horizontal direction to that in vertical direction increases remarkably. 1.INTRODUCTION Tunnels and bridges cannot always be used to connect the places...

... ABSTRACT Hollow rectangular camber otter board was mainly adopted in low-speed trawl systems in Antarctic krill fisheries. In this study, hydrodynamic analyses were performed on a hollow rectangular camber otter board with a projected area of 13.02 square meters, an aspect ratio (AR) of 1.66...
