The synergistic action and interplay of hydrogen embrittlement mechanisms in steels and iron: Localized plasticity and decohesion
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Component failures due to the hydrogen embrittlement (HE) were observed in different industrial systems, including high-pressure hydrogen storage tanks, aircraft components, high-strength alloy components, and high-strength ...
Multi-objective design optimization strategies for small-scale vertical-axis wind turbines
(Springer, New York, 2016)
Extracting energy from wind has been an interesting and serious topic over the last few decades and a lot of work has been done on the subject. This paper discusses in detail possible approaches to optimization of a somewhat ...
Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models
(Natl Assoc Corrosion Eng, Houston, 2016)
Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. In practice, it is observed that different types of damage to industrial components have been tied to the presence ...
Life Cycle Impact Assessment of Miscanthus Crop for Sustainable Household Heating in Serbia
(MDPI, Basel, 2018)
This paper investigates the environmental impacts and energy benefits of the cultivation of Miscanthus (Miscanthus x giganteus Greef et Deu.), in order to initiate its use in sustainable household heating in the Republic ...
Butt welded joints assessment after fire exposure
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. In many cases, after structural safety assessment, fire exposed ...
Effects of a low-Shrinkage methacrylate monomer and monoacylphosphine oxide photoinitiator on curing efficiency and mechanical properties of experimental resin-based composites
(Elsevier, Amsterdam, 2016)
This study investigated the degree of conversion, depth of cure, Vickers hardness, flexural strength, flexural modulus and volumetric shrinkage of experimental composite containing a low shrinkage monomer FIT-852 (FIT; ...
Effect of laser beam welded reinforcement on integral skin panel fatigue life
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, numerical analyses of fatigue crack growth in integral skin-stringer panel produced by means of laser beam welding (LBW) are presented along with fatigue results verified by previously conducted experiments. ...
Numerical analysis of fatigue crack growth of hip implant
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
Fatigue crack growth in hip implant has been analysed using the extended finite element method. Toward this aim, the three-dimensional finite element model is created and used in ABAQUS and Morfeo/crack add-in for ABAQUS ...
Determination of optimum wing spar cross section for maximum fatigue life
(Elsevier Sci Ltd, Oxford, 2019)
Shape optimisation is a nowadays-standard requirement in the design of lightweight structural components. In this paper, optimisation of I-beam cross-section of integral aluminium 2024-T3 wing spar is presented, taking the ...
Thermal-hydraulics of helium cooled First Wall channels and scoping investigations on performance improvement by application of ribs and mixing devices
(Elsevier Science Sa, Lausanne, 2016)
The first wall (FW) of DEMO is a component with high thermal loads. The cooling of the FW has to comply with the material's upper and lower temperature limits and requirements from stress assessment, like low temperature ...
