The tensile ductility of cellular solids: the role of imperfections
(Elsevier, 2016-10-11)
Metallic and polymeric foams typically possess a low tensile failure strain of a few percent despite the fact that the parent solid can have high ductility (10% or more). This is remarkable as foams are bending-dominated ...
Micromechanical finite element modelling of thermo-mechanical fatigue for P91 steels,
(Elsevier, 2016-01-21)
In this paper, the cyclic plasticity and fatigue crack initiation behaviour of a tempered martensitic ferritic steel under thermo-mechanical fatigue conditions is examined by means of micromechanical finite element modelling. ...
Computational investigation of in situ chondrocyte deformation and actin cytoskeleton remodelling under physiological loading
(Elsevier, 2012-12-24)
Previous experimental studies have determined local strain fields for both healthy and degenerate cartilage tissue during mechanical loading. However, the biomechanical response of chondrocytes in situ, in particular the ...
The effect of remodelling and contractility of the actin cytoskeleton on the shear resistance of single cells: a computational and experimental investigation
(The Royal Society Publishing, 2012-07-18)
The biomechanisms that govern the response of chondrocytes to mechanical stimuli are poorly understood. In this study, a series of in vitro tests are performed, in which single chondrocytes are subjected to shear deformation ...
Cellular contractility and substrate elasticity: a numerical investigation of the actin cytoskeleton and cell adhesion
(Springer Verlag, 2013-06-18)
Numerous experimental studies have established that cells can sense the stiffness of underlying substrates and have quantified the effect of substrate stiffness on stress fibre formation, focal adhesion area, cell traction, ...
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)
In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ...
A critical analysis of plastic flow behaviour in axisymmetric isothermal and Gleeble compression testing
(Elsevier ScienceDirect, 2010-08-16)
Coupled thermo-mechanical finite element modelling of both isothermal axisymmetric compression and compression testing using the Gleeble thermo-mechanical simulator has been carried out in order to compare the levels of ...
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-07)
Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ...
A preliminary design methodology for fatigue life prediction of polymer composites for tidal turbine blades
(SAGE, 2012-06-06)
Tidal turbine blades experience significant fatigue cycles during operation and it is expected that fatigue strength will be a major consideration in their design. Glass fibre reinforced polymers are a candidate low-cost ...
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 ...
