Cyclic plasticity of welded P91 material for simple and complex power plant connections
(Elsevier, 2016-02-10)
This paper focuses on with the cyclic plasticity modelling of welded, ex-service P91 material. A multi material model is developed for high temperature cyclic plasticity, including the effects of the three different material ...
Use of non-destructive test methods on Irish hardwood standing trees and small-diameter round timber for prediction of mechanical properties
(Springer Verlag, 2020-06-17)
Key message Mechanical properties of small-diameter round timber from hardwood thinnings of common alder (Alnus glutinosa (L.) Gaertn.), European ash (Fraxinus excelsior L.), European birch (Betula pendula Roth. & Betula ...
Effect of high-temperature corrosion on the service life of P91 piping in biomass co-firing
(American Society of Mechanical Engineers (ASME), 2016-02-24)
Co-firing biomass with traditional fuels is becoming increasingly relevant to thermal power plant operators due to increasingly stringent regulations on greenhouse gas emissions. It has been found that when biomass is ...
A two and three-dimensional CFD investigation into performance prediction and wake characterisation of a vertical axis turbine
(AIP Publishing, 2018-05-24)
The emergence of tidal energy as a key renewable energy source requires the development of computational design models for accurate prediction of turbine performance and wake effects whilst also being computationally ...
Does making method of alginate hydrogel influence the chondrogenic differentiation of human mesenchymal stem cells?
(Scientific Research Publishing, 2012-10)
To overcome cartilage injury, strategies have been developed in the last few years based on tissue engineering to rebuild the defects. Cartilage engineering is principally based on three main biological factors: cells ...
A strain-gradient, crystal plasticity model for microstructure-sensitive fretting crack initiation in ferritic-pearlitic steel for flexible marine risers
(Elsevier, 2018-02-03)
A three-dimensional, strain-gradient, crystal plasticity methodology is presented for prediction of microstructure-sensitive length-scale effects in crack initiation, under fatigue and fretting fatigue conditions, for a ...
Chondrogenic induction of mesenchymal stromal/stem cells from Wharton's jelly embedded in alginate hydrogel and without added growth factor: an alternative stem cell source for cartilage tissue engineering
(BioMed Central, 2015-12-30)
Background: Due to their intrinsic properties, stem cells are promising tools for new developments in tissue engineering and particularly for cartilage tissue regeneration. Although mesenchymal stromal/stem cells from bone ...
Primary cilia expression in bone marrow in response to mechanical stimulation in explant bioreactor culture
(AO Research Institute Davos, 2016-07-19)
Bone marrow contains a multitude of mechanically sensitive cells that may participate in mechanotransduction. Primary cilia are sensory organelles expressed on mesenchymal stem cells (MSCs), osteoblasts, osteocytes, and ...
A physically-based constitutive model for high temperature microstructural degradation under cyclic deformation
(Elsevier, 2017-03-23)
This paper presents a dislocation-mechanics cyclic viscoplasticity model which incorporates the key physical micro-mechanisms of strengthening and softening for high temperature deformation of 9Cr steels. In particular, ...
Osteocyte differentiation and the formation of an interconnected cellular network in vitro
(AO Research Institute Davos, 2016-05-26)
Extracellular matrix (ECM) stiffness and cell density can regulate osteoblast differentiation in two dimensional environments. However, it is not yet known how osteoblast-osteocyte differentiation is regulated within a 3D ...
