Using Wikis to facilitate team work: German and Irish students' perspectives
(All Ireland Society for Higher Education (AISHE), 2011)
Enhanced collaboration among multicultural European countries is necessary for effective
enterprise development and innovation. The current climate of an increasingly competitive
global economy provides opportunities to ...
A Multiaxial Fatigue Damage Model for Fibre Reinforced Polymer Composites
(Elsevier (Scienc Direct), 2013)
A multiaxial fatigue damage model for fibre reinforced polymercomposite materials is presented. The model combines (i) fatigue-induced fibre strength and modulus degradation, (ii) irrecoverable cyclic strain effects and ...
Experimental and numerical characterisation of the cyclic thermo-mechanical behaviour of a high temperature forming tool alloy
(American Society of Mechanical Engineers, 2010-10-05)
This paper describes high temperature cyclic and creep relaxation testing and modeling of a high nickel-chromium material (XN40F) for application to the life prediction of superplastic forming (SPF) tools. An experimental ...
Overview of the regulation of medical devices and drugs in the European Union and the United States
(SAGE Publications, 2013-08-06)
This article provides an overview of the regulation of medical devices and drugs in the European Union and the US. It is important for all stakeholders involved in bringing a medical device or drugs to market to have an ...
Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)
In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ...
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 ...
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 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 ...
