Finite bending and pattern evolution of the associated instability for a dielectric elastomer slab
(Elsevier, 2018-09-21)We investigate the finite bending and the associated bending instability of an incompressible dielectric slab subject to a combination of applied voltage and axial compression, using nonlinear electro-elasticity theory and ... -
Finite element modelling for component-level additive manufacturing applied to residual stress-deformation mitigation and fatigue crack initiation in welded connections
(NUI Galway, 2023-08-21)Additive manufacturing (AM) has attracted significant attention in many applications due to its capability of fabricating complex and customized metal parts. However, the potential for high inherent residual stresses ... -
Finite element modelling for mitigation of residual stress and distortion in macro-scale powder bed fusion components
(SAGE Publications, 2022-12-23)Powder bed fusion (PBF) has attracted significant attention in many applications due to its capability of fabricating complex and customized metal parts. However, the potential for high inherent residual stresses that ... -
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 ... -
Finite element modelling of damage in superplastic forming of a titanium alloy
(Springer Verlag, 2009-12-15)This paper describes the application of a continuum damage mechanics methodology to the prediction of failure during superplastic forming of Ti-6Al-4V. A power law constitutive relationship is employed within a geometrically ... -
Finite element modelling of the thermo-mechanical behaviour of a 9Cr martensitic steel
(Springer, Berlin, Heidelberg, 2013-01-01)A multi-axial, unified sinh viscoplastic material model has been developed to model the behaviour of advanced materials subjected to high temperature cyclic loading. The material model accounts for rate-dependent effects ... -
Finite element prediction of creep-plastic ratchetting and low cycle creep-fatigue for a large SPF tool
(Springer Verlag, 2010-03-03)Industrial experience shows that large superplastic forming (SPF) tools suffer from distortion due to thermal cycling, which apparently causes high temperature creep and plasticity. In addition to distortion, thermomechanical ... -
Finite element predictions compared to experimental results for the effective modulus of bone tissue engineering scaffolds fabricated by selective laser sintering
(Springer Verlag, 2009)A current challenge in bone tissue engineering is to create scaffolds with suitable mechanical properties, high porosity, full interconnectivity and suitable pore size. In this paper, polyamide and polycaprolactone scaffolds ... -
Finite element simulation and experimental validation of fretting wear
(Elsevier, 2003-10-30)A finite element-based method is presented for simulating both the fretting wear and the evolution of fretting variables with number of wear cycles in a cylinder-on-flat fretting configuration for application to aeroengine ... -
Finite element simulation of fretting wear and fatigue in thin steel wires
(Elsevier ScienceDirect, 2013-05-09)This paper studies the effect of fretting on fatigue life reduction of thin steel wires, using the frictionally-induced multiaxial contact stresses obtained from a finite element wear model, validated in previous work. The ... -
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) ... -
A finite element-based approach for predictions of rigid pile group stiffness efficiency in clays
(Springer Verlag, 2013-08-17)This paper presents a finite element parametric study of several variables that affect the stiffness efficiency of rigidly capped pile groups with a view to developing a solution for preliminary design purposes. Previous ... -
Finite frequentism in a big world
(Oxford University Press (OUP), 2014-11-28)The view that chances are relative frequencies of occurrence within actual, finite reference classes has long been written off. I argue that it ought to be reconsidered. Focusing on non-deterministic chance, I defend a ... -
The finite implication problem for expressive XML keys: Foundations, applications, and performance evaluation
(Springer, 2013)The increasing popularity of XML for persistent data storage, processing and exchange has triggered the demand for efficient algorithms to manage XML data. Both industry and academia have long since recognized the importance ... -
Finite rigid sets in curve complexes
(World Scientific Pub Co Pte Lt, 2013-06-01)We prove that curve complexes of surfaces are finitely rigid: for every orientable surface S of finite topological type, we identify a finite subcomplex X of the curve complex C(S) such that every locally injective simplicial ... -
Finite-amplitude inhomogeneous plane waves in a deformed Mooney-Rivlin material
(Oxford University Press, 2002)The propagation of finite-amplitude linearly-polarized inhomogeneous transverse plane waves is considered for a Mooney-Rivlin material maintained in a state of finite static homogeneous deformation. It is shown that such ... -
Finite-amplitude inhomogeneous plane waves of exponential type in incompressible elastic materials
(Kluwer Academic Publishers, 1999-05)It is proved that elliptically polarized finite-amplitude inhomogeneous plane waves may not propagate in an elastic material subject to the constraint of incompressibility. The waves considered are harmonic in time and ... -
Finite-amplitude Love waves in a pre-stressed neo-Hookean material
(2008)In the context of the non-linear elasticity theory we consider a model for compressible solids called compressible neoHookean material . We show how (exact) finite-amplitude inhomogeneous plane wave solutions and ... -
Finn’s Seat: topographies of power and royal marchlands of Gaelic polities in medieval Ireland
(Taylor & Francis, 2017-10-31)Hill- and mountain-top cairns and mounds in Ireland are often viewed as epiphenomenal features of the medieval landscape. In recent years, research on early medieval ferta, ancestral burial places cited in the legal procedure ... -
