Evaluating the effect of increasing ceramic content on the mechanical properties, material microstructure and degradation of selective laser sintered PCL/b-TCP materials
(Elsevier, 2015-06-06)
Orthopaedic scaffold materials were fabricated from polycaprolactone (PCL) and composite PCL β-tricalcium phosphate (PCL/β-TCP) powders using selective laser sintering (SLS). Incorporating β-TCP particles is ...
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 ...
A thermodynamically motivated model for stress-fiber reorganization
(Springer Verlag, 2015-09-04)
We present a model for stress-fiber reorganization and the associated contractility that includes both the kinetics of stress-fiber formation and dissociation as well as the kinetics of stress-fiber remodeling. These ...
Evaluation of a multiscale modelling methodology to predict the mechanical properties of PCL/β-TCP sintered scaffold materials
(Springer Verlag, 2014-12-02)
A multiscale modelling methodology to predict the macroscale stiffness of selective laser sintered polycaprolactone (PCL)/β-tricalcium phosphate (β-TCP) materials is evaluated. The relationship between a micromechanics-evaluated ...
A unified viscoplastic model for high temperature low cycle fatigue of service-aged P91 steel
(American Society of Mechanical Engineers, 2014-01-07)
The finite element (FE) implementation of a hyperbolic sine unified cyclic viscoplasticity model is presented. The hyperbolic sine flow rule facilitates the identification of strain-rate independent material parameters for ...
Improving the finite element model accuracy of tissue engineered scaffolds produced by selective laser sintering
(Springer Verlag, 2015-01-13)
In bone tissue engineering, both geometrical and mechanical properties of a scaffold play a major part in the success of the treatment. The mechanical stresses and strains that act on cells on a scaffold in a physiological ...
