Evaluation of the mechanical properties of the heat treated FeCrCuMnNi high entropy alloy

Roland Logé, Ali Shabani

As cast FeCrCuMnNi high entropy alloys were heat treated at different temperatures and times. Structure and mechanical properties of the heat treated alloy were studied using X-Ray diffraction, tensile test, hardness test and scanning electron microscopy. ...

Experimental Assessment of the Impact of Partial Saturation On the Mechanical Properties of Gas Shales

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

The impact of partial water saturation on the mechanical behaviour of clays and claystones has been widely proved. This work aims at demonstrating that also for gas shales partial water saturation has a significant influ-ence on their stiffness and strengt ...

Energy piles, due to their dual roles, are exposed to temperature change throughout their life time, which may cause axial displacements, additional axial stresses and changes in the shaft resistance along their lengths. The extent of these effects highly ...

ELSEVIER SCIENCE BV2019

Beetles are by far one of the most successful groups of insects, with large diversity in terms of number of species. A part of this success is attributed to their elytra, which provide various functions such as protection to their bodies from mechanical fo ...

Deformation and degradation of superelastic NiTi under multiaxial loading

Helena Van Swygenhoven, Steven Van Petegem, Efthymios Polatidis, Nicola Casati, Wei-Neng Hsu

The degradation of the superelastic properties of a commercial NiTi alloy is studied during uniaxial, biaxial and load-path-change cycling performed in-situ with synchrotron X-ray diffraction. Careful examination of the diffraction pattern during uniaxial ...

Test and lower bound modeling of keyed shear connections in RC shear walls

Aurelio Muttoni, Cao Linh Hoang, Jesper Harrild Sorensen

This paper presents an investigation into the ultimate behavior of a recently developed design for keyed shear connections. The influence of the key depth on the failure mode and ductility of the connection has been studied by push-off tests. The tests sho ...

The Consensus-halving problem is the problem of dividing an object into two portions, such that each of n agents has equal valuation for the two portions. We study the epsilon-approximate version, which allows each agent to have an epsilon discrepancy on t ...
