Study on the Steepness of Landslide-Induced Wave and Nonlinear Motion of Container Ships

Applied Sciences, 2020
Large-scale instability of a landslide body, sliding down a bank slope and entering water at a high speed, arouses landslide surges. Taking the water entry point as a source point, they spread rapidly to surrounding areas, increasing the danger risk of ...

Roll up! Roll up! [PDF]

Index on Censorship, 2001
Vladimir Bukovsky was first arrested in 1963 for the possession of anti-Soviet literature and interned in a special psychiatric hospital for 14 months. In 1965, he was rearrested for co-organising a Moscow human rights demonstration in defence of writers Andrei Sinyavsky and Yulii Daniel, and sent to a series of mental hospitals.

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

Advanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Numerical Analysis of Roll Hydrodynamic Coefficients of 2D Triangular Cylinder Using OpenFOAM

Journal of Marine Science and Engineering
Predicting the roll damping coefficient of a ship is a crucial factor in determining the dynamic stability of the vessel. However, a nonlinear analysis that considers the viscosity of the fluid is required to accurately estimate the roll damping ...
