Sediment Load under Waves and Currents

open access: yesCoastal Engineering 1978, 1978
A technique is proposed for calculating sediment load, the mass concentration of sediment in motion, under combinations of waves and currents. The technique is based on the unidirectional flow method of Ackers and White, Ref. 1. The calibration of the technique against measurements of sediment load under waves has only just begun.

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.

Influence of local scour on the dynamic responses of OWTs under wind-wave loads

open access: yesFrontiers in Marine Science
Offshore wind turbines (OWTs) often operate in complex marine environments, where they are not only subjected to wind and wave loads, but also adversely affected by scour.

Experimental validation of parked loads for a floating vertical axis wind turbine: wind–wave basin tests [PDF]

open access: yesWind Energy Science
Parked loads are a major design load case for vertical axis wind turbines (VAWTs) because of persistent high loads on the rotor when in standstill conditions.

A numerical and experimental study of internal solitary wave loads on semi-submersible platforms

open access: yes, 2018
Using a double-plate wave maker, a series of laboratory experiments of internal solitary wave (ISW) loads on semi-submersible platforms were conducted in a density stratified fluid tank.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

open access: yesAdvanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Study on the Wave Loads and Structural Stresses of Container Ship

open access: yesJournal of Physics: Conference Series, 2018
In this article ship motions and wave loads are analyzed by using three dimensional motion of the ship program. As an example of a 5500TEU container ship, the heading angles of maximum motions and loads, amplitude of movement under the action of unit ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Advances in the study of internal solitary waves and their interaction with marine structures

open access: yesZhongguo Jianchuan Yanjiu
Internal solitary waves (ISWs) are a common nonlinear, large-amplitude fluctuation phenomenon which is widely present in densely stratified oceans and can induce the shear state of the seawater flow above and below the wave surface during the propagation
