Fatigue life of pitch- and stall-regulated composite tidal turbine blades
Tidal turbine blades are subject to harsh loading and environmental conditions, including large thrust and torsional loadings, relative to wind turbine blades, due to the high density of seawater, among other factors. The ...
A physically-based high temperature yield strength model for 9Cr steels
The strength of 9Cr steels, which is controlled by chemical composition and microstructure, evolves significantly under high temperature loading. This paper presents a temperature-independent, physically-based model for ...
The effect of inclusions on the high‐temperature low‐cycle fatigue performance of cast MarBN: Experimental characterisation and computational modelling
The presence of inclusions is a known source of crack initiation and component failure in cast materials. In this work, the role of inclusions is investigated via a combined program of high-temperature low-cycle fatigue ...
Influence of microstructural defects and hydrostatic pressure on water absorption in composite materials for tidal energy
(SAGE Publications, 2018-01-06)
The lifespan and economic viability of tidal energy devices are constrained, in part, by the complex degradation of the tidal turbine blade materials due to prolonged immersion in a hostile sub-sea environment. Seawater ...
