“…As shown in Hata! Başvuru kaynağı bulunamadı., the agreement is nearly exact except for the initial plastic deformation as it is a common observation in the crystal plasticity modelling (Bal, 2018, Bal et al, 2016, and it indicates that the numerical solution is adequate in predicting the stresses during cutting of Inconel 718. The experimental results proved that, the modelling of material deformation has been successfully carried out.…”

“…The viscoplastic self-consistent (VPSC) model written in FORTRAN 77 was utilized to obtain a material model that captures the microstructural features (Lebensohn and Tomé, 1993). In particular, hardening parameters on the slip system level were determined by means of uniaxial stress-strain response (Bal et al 2018(Bal et al , 2016. Equivalent stress-strain responses of Inconel 718 for each cutting speed and feed combinations were then computed using the same hardening parameters and velocity gradients via the finite element modelling software.…”

This study presents the dynamic and buckling analysis of the laminated composite thin arch plate frame structures employing Classical Plate Theory with Finite Element Analysis. For this purpose, the effects of the radius of curvature, aspect ratio, and stacking order of such structures on the first ten natural frequencies, mode shapes, critical buckling load, and the first unstable regions are investigated. Besides, the two-bay curved plate frame structure is investigated. In order to perform dynamic and buckling analyses, a computer code is developed and executed via MATLAB. The results are compared and validated with those of ANSYS. It is concluded that the aspect ratio or the stacking order affects the dynamic characteristics of the curved plate frame structure considerably while the radius of curvature relatively has less impact on such dynamic properties of the structure.

“…First, the micro-hardness of the PcBN with Ti 3 Al and TiAl as the binders was low. Second, environmental hydrogen embrittlement caused by harmful gases (H 2 O, H 2 ) at room temperature on metals and intermetallic is universal [41,42]. The active elements Ti and Al in Ti 3 Al and TiAl react with the water vapour or hydrogen and produce hydrogen atoms.…”

Polycrystalline cubic boron nitride (PcBN) was sintered in the temperature range of 1050-1650°C under an ultra-high pressure of 5.0 GPa for 20 min using an in situ synthesis method. X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy and energydispersive spectrometry were used to study the compositional and morphological changes during the synthetic process. The results showed that rod-shaped TiB 2 crystals could be detected at 1150°C, and their quantity increased with sintering temperatures. The TiB 2 crystals distributed homogeneously and grew randomly among the cBN grain boundaries and interstitial spaces, ultimately forming an interlocking structure. The PcBN prepared at 1650°C exhibited optimal comprehensive mechanical properties, with a micro-hardness of 44.42 GPa and a flexural strength of 862.5 MPa. Moreover, based on the experimental results, the chemical reaction mechanism and the strengthening mechanisms occurred during the sintering process were also proposed to properly interpret the synthesis of PcBN.

“…Hydrogen is a highly reactive gas that causes metals corrosion, especially since the low atomic radius of hydrogen enables it to penetrate deep inside structures, including metal structures, even under standard conditions. Thus, a degradation of the mechanical properties of materials exposed to such an aggressive environment can be observed [22]. The BPs degradation may lead, among other detrimental phenomena, to a voltage drop increase due to the rise in the contact resistance.…”

The latest pre-production vehicles on the market show that the major technical challenges posed by integrating a fuel cell system (FCS) within a vehicle—compactness, safety, autonomy, reliability, cold starting—have been met. Regarding the ongoing maturity of fuel cell systems dedicated to road transport, the present article examines the advances still needed to move from a functional but niche product to a mainstream consumer product. It seeks to address difficulties not covered by more traditional innovation approaches. At least in long-distance heavy-duty vehicles, fuel cell vehicles (FCVs) are going to play a key role in the path to zero-emissions in one or two decades. Hence the present study also addresses the structuring elements of the complete chain: the latter includes the production, storage and distribution of hydrogen. Green hydrogen appears to be one of the potential uses of renewable energies. The greener the electricity is, the greater the advantage for hydrogen since it permits to economically store large energy quantities on seasonal rhythms. Moreover, natural hydrogen might also become an economic reality pushing the fuel cell vehicle to be a competitive and environmentally friendly alternative to the battery electric vehicle. Based on its own functional benefits for on board systems, hydrogen in combination with the fuel cell will achieve a large-scale use of hydrogen in road transport, as soon as renewable energies become more widespread. Its market will expand from large driving range and heavy load vehicles.
