Microscale flow structures measured downstream of a mechanical heart valve
(Trinity College Dublin, 2010-01-22)
A finite element study of microstructure-sensitive plasticity and crack nucleation in fretting
(Elsevier ScienceDirect, 2011)
This paper is concerned with finite element modelling of microstructure-sensitive plasticity and crack initiation in fretting. The approach adopted is based on an existing method for microstructure-sensitive (uniaxial) ...
Microstructure-sensitive prediction and experimental validation of fretting fatigue
(Elsevier ScienceDirect, 2013-06-03)
This paper is concerned with the development of a micro-mechanical methodology for prediction of fretting fatigue crack nucleation life and short crack propagation. The methodology employs critical accumulated plastic slip ...
Micromechanical modelling of fatigue crack nucleation in stents
(Bioengineering In Ireland Conference 2012, 2012)
A finite element based micro-mechanical methodology for cyclic plasticity and fatigue crack initiation in cardiovascular stents is presented. The methodology is based on the combined use of a (global) three-dimensional ...
A review of the integrity of metallic vehicle armour to projectile attack
(SAGE Publications, 2018-02-28)
This article presents a review of engineering and design aspects relevant to the mechanical and structural integrity of military vehicular armour, including materials-related technologies. Theoretical, experimental and ...
Gross slip fretting wear performance of a layered thin W-DLC coating: damage mechanisms and life modelling
(Elsevier ScienceDirect, 2011)
Fretting damage, in the form of wear and fatigue-cracking, is a common cause for concern in a wide range of dynamically loaded mechanical joints, and consequently, control of the rates of such damage is commonly addressed ...
A combined wear-fatigue design methodology for fretting in the pressure armour layer of flexible marine risers
(Elsevier, 2016-10-20)
This paper presents a combined experimental and computational methodology for fretting wear-fatigue prediction of pressure armour wire in flexible marine risers. Fretting wear, friction and fatigue parameters of pressure ...
Comparing how entrepreneurs and managers represent the elements of the business model canvas
(Elsevier, 2018-03-03)
This paper uses self-efficacy to compare how entrepreneurs and managers represent the nine elements of the business model canvas (BMC; Osterwalder, 2004). A six-item efficacy scale was developed to measure each element. ...
A combined XFEM and cohesive zone model for composite laminate microcracking and permeability
(Elsevier ScienceDirect, 2014-10-07)
A novel computational methodology for predicting three-dimensional microcracking and permeability in composite laminates is presented, The methodology simulates microcrack initiation and propagation using the extended ...
Finite element modelling of brittle fracture of thick coatings under normal and tangential loading
(Elsevier ScienceDirect, 2012-09-12)
This paper addresses coating fracture in hard brittle coatings subjected to combined normal and tangential loads through a finite element based methodology. The coating is modelled as an elastic layer perfectly bonded to ...
