A practical framework for strategic noise mapping
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008)Environmental noise is a major form of pollution and it is estimated that at least one quarter of the population of the EU suffer a reduced quality of life due to exposure to noise. To address the problem the European Union ... -
An investigation into the influence of cardiovascular stent design on the development of restenosis using the finite element method
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)Finite element models, which can determine the degree of vascular injury caused to a vessel by a stent and hence ascertain the propensity of that stent design to cause in¬stent restenosis, would be a valuable tool for both ... -
Analysis of noise source mechanisms for a subsonic jet
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006)Despite advances in engine design, from high bypass to co-axial or lobe shaped nozzles, the problem of jet noise reduction continues to require ongoing research in order to comply with the criteria inherent in environmental ... -
Aspects of the fatigue behaviour of acrylic bone cement
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2002)Polymethylmethacrylate bone cement is used to fixate many orthopaedic implants. However, it is a brittle material, prone to damage accumulation leading to cement cracking and prosthesis loosening. The damage accumulation ... -
Interaction between fluidelastic instability and acoustic resonance

Iterative three-dimensional Helmholtz Equation solutions using the Wave Expansion Method
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)Modelling sound propagation often can present difficult challenges due to computational demands. In general, the direct solutions of the system equations arising from the full field discretization of many three-dimensional ... -
Multivariate statistical methods for fault detection and classification
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2006) -
Numerical vibro/acoustic analysis at higher frequencies
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)Accurate modelling of steady-state acoustic and elastic wave phenom ena at higher frequencies, represents a major challenge for current numerical tools. Due to the large amount of computational effort and memory resources ... -
Passive mechanical properties of skeletal muscle in compression
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2007)The compressive properties of skeletal muscle are of prime interest in applications where muscle tissue is submitted to compressive loads; e.g., to improve the design of protective equipment for vehicular occupants, to ... -
Simulation of bone fracture and cutting using the theory of critical distances
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2008)This work was concerned with the prediction of bone fracture in situations where fracture was initiated in areas of stress concentration. Two conditions were studied: (i) fracture in bones and bone samples weakened by the ... -
The cellular transducer in damage-stimulated bone remodelling
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2004)People with osteoporosis, osteopenia or weight baring joint replacement, due to an altered loading configuration, are more susceptible to microdamage accumulation than normal human beings as are athletes who undertake ... -
The fatigue behaviour of three-dimensional stress concentrations
(Trinity College (Dublin, Ireland). Department of Mechanical and Manufacturing Engineering, 2003)The fatigue behaviour of complex three-dimensional notched components is a subject of great practical interest to industrial engineers. Unfortunately, the analysis of this type of feature presents problems for most assessment ...
