Computational modelling of ovine critical-sized tibial defects with implanted scaffolds and prediction of the safety of fixator removal
Doyle, Heather; Lohfeld, Stefan; Durselen, Lutz; McHugh, Peter (Elsevier, 2015-01-14)Computational model geometries of tibial defects with two types of implanted tissue engineering scaffolds, β-tricalcium phosphate (β-TCP) and poly-ε-caprolactone (PCL)/β-TCP, are constructed from µ-CT scan images of the ... -
Evaluating the effect of increasing ceramic content on the mechanical properties, material microstructure and degradation of selective laser sintered PCL/b-TCP materials
Doyle, Heather; Lohfeld, Stefan; McHugh, Peter E. (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 ... -
Evaluation of a multiscale modelling methodology to predict the mechanical properties of PCL/β-TCP sintered scaffold materials
Doyle, Heather; Lohfeld, Stefan; McDonnell, Pat; McHugh, Peter E. (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 ... -
Improving the finite element model accuracy of tissue engineered scaffolds produced by selective laser sintering
Lohfeld, Stefan; Cahill, Senan; Doyle, Heather; McHugh, Peter E. (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 ...
