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; ...
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 ...
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 ...
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. ...
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 ...
Fracture mechanics and fatigue crack propagation in armor steel welds
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The welding process of armor steel is a complex process due to possible welding faults appearing in all zones of weld metal joint in the form of cracks and pores, as results of high percentage of carbon in the base metal. ...
Influence of welded joint microstructures on fatigue behaviour of specimens with a notch in the heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In this paper, the results of determining the Paris law coefficients, C and m, are presented, based on the experimental data obtained by three-point bending testing of 8 welded joint specimens. The specimens were taken ...
Chaotic fruit fly optimization algorithm
(Elsevier, Amsterdam, 2015)
Fruit fly optimization algorithm (FOA) is recently presented metaheuristic technique that is inspired by the behavior of fruit flies. This paper improves the standard FOA by introducing the novel parameter integrated with ...
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 ...
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 ...
