Analysis of the mechanical performance of a biodegradable magnesium stent in a remodelling artery
(NUI Galway, 2018-09-28)Coronary stents made from degradable biomaterials such as magnesium alloy are an emerging technology in the treatment of coronary artery disease. Biodegradable stents provide mechanical support to the artery during the ... -
Are all osteocytes equal? Multiscale modelling of cortical bone to characterise the mechanical stimulation of osteocytes
(Wiley, 2013-12-03)Bone continuously adapts its internal structure to accommodate the functional demands of its mechanical environment. This process is orchestrated by a network of mechanosensitive osteocytes that respond to external ... -
A combined experimental-numerical approach for generating statistically equivalent fibre distributions for high strength laminated composite materials
(Elsevier, 2009-11-04)A technique is presented where actual experimental distributions, measured from a high strength carbon fibre composite, are considered in the development of a novel method to generate statistically equivalent fibre ... -
Computational modelling of ovine critical-sized tibial defects with implanted scaffolds and prediction of the safety of fixator removal
(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 ... -
Demonstrating a linked data visualiser for finite element biosimulations
(IEEE, 2016-02-04)Healthcare experts have recently turned towards the use of Biosimulation models to understand the multiple or different causative factors that cause impairment in human organs. The applications of biosimulations have been ... -
The effect of slip regime on fretting wear-induced stress evolution
(Elsevier, 2004-02-20)A numerical approach to simulate fretting wear, based on a modified version of the Archard equation, is applied to a cylinder-on-flat fretting configuration for gross sliding and partial slip conditions. The evolution of ... -
Engineering assisted surgery: A route for digital design and manufacturing of customized maxillofacial implants
(Elsevier, 2007)Rapid prototyping (RP) and more recently rapid manufacturing (RM) as a part of Engineering Assisted Surgery enables manufacturing of customised implants and prostheses prior to surgical procedures. Beginning with CT ... -
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 ... -
An experimental and numerical study of moisture flow and moisture-induced strain in fast-grown Sitka spruce
(Departamento de Ingeniería en Maderas de la Universidad del Bio-Bio en Concepción, Chile, 2019)The use of fast-grown timber in the manufacture of engineered wood products is increasing; however, the fast growth rate results in a low-density timber that is susceptible to significant swelling and shrinkage deformations ... -
Fluid flow in the osteocyte mechanical environment: a fluid-structure interaction approach
(Springer Verlag, 2013-04-09)Osteocytes are believed to be the primary sensor of mechanical stimuli in bone, which orchestrate osteoblasts and osteoclasts to adapt bone structure and composition to meet physiological loading demands. Experimental ... -
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 ... -
An investigation of the inelastic behaviour of trabecular bone during the press-fit implantation of a tibial component in total knee arthroplasty
(Institute of Physics and Engineering in Medicine by Elsevier Ltd., 2013)The stress distribution and plastic deformation of peri-prosthetic trabecular bone during press-fit tibial component implantation in total knee arthroplasty is investigated using experimental and finite element techniques. ... -
