Development of advanced numerical models for concentrically braced steel frame members and components
(NUI Galway, 2018-09-18)The behaviours of braced steel frame members and components are investigated in this project using finite element models that were developed to address the multi-scale mechanics of braced steel frame structures. The ... -
The development of an online intervention for post-treatment cancer survivors with cancer-related fatigue
(2017-02-02)Background The number of post-treatment cancer survivors in Ireland is set to increase in coming years, due to advances in screening and treatment. This group will require ongoing supportive care as many will experience ... -
An experimental and computational investigation of the high temperature behaviour of MarBN steel with application to effects of manufacturing
(NUI Galway, 2018-10-30)The key step for next generation power plants is the development of advanced materials capable of achieving high flexibility and efficiency at increased steam temperatures and pressures. Such operating conditions will cause ... -
Experimental characterisation, computational modelling and design tool development for fretting fatigue and wear in flexible marine risers
(2017-09-25)Fretting is a key concern in the fatigue design of the pressure armour layer of flexible marine risers, due to the combination of extreme global dynamic loading conditions and the local geometrical-tribological conditions ... -
Geometry effect in the fatigue behaviour of microscale 316L stainless steel specimens
(2012-06-07)Advances in engineering fabrication technology permit the manufacture of microscale components and devices. These tiny products are used in a wide range of applications, from medical devices to smart phones. There are ... -
Modelling the mechanical and fatigue behaviour of superelastic NiTi: analysing the role of microstructural phase and crystallographic texture
(2015-08-26)Superelastic NiTi self-expanding stents push the boundaries of our current understanding of material behaviour which ultimately influences the design of biomedical devices. In particular, the influence of microstructure ... -
Process-structure-property characterisation of plasticity and fatigue damage in X100 welded joints for steel catenary risers
(NUI Galway, 2020-04-02)Steel catenary risers are increasingly used for offshore oil and gas production due to their suitability for deep and ultra-deepwater installation, in terms of structural capacity and capital expenditure requirements. ... -
Seismic Design of Concentrically Braced Steel Frames
(2012-03-01)The aim of this project is to develop a robust numerical model that accurately replicates the behaviour of CBFs during earthquakes. This numerical model is then used to validate a codified performance based design approach ...
