An influence of normal stresses acting on the shear plane is evidenced by: (i) the fracture angle (<45°) and (ii) finite-element simulations of nanoindentation curves, which require the use of a specific yield criterion, sensitive to local normal stresses acting on the shear plane, to ...
A consequence of having a larger amount of a refractory element, such as tungsten, in the alloy can be the existence of unmelted tungsten-rich phases that are prone to nucleation during casting. The combination of chromium and molybdenum elements in the Fe-based alloy improves the GFA and at...
The eutectic temperature is reduced by nearly 50 K relative to that of the binary eutectic, demonstrating the significant role of the third element Al in stabilizing the liquid. The fragility parameterD* of the Cu55Hf45binary and Cu49Hf42Al9ternary supercooled liquid was determined from ...
6. Finite element analysis The quasi-static compressive collapse of the origami specimens was simulated using the commercial finite element package Abaqus Standard. The aim of this numerical study is to interrogate the accuracy of finite element predictions of the collapse response for these SLM-manufa...

Understanding the complex metallic element Mn.II. Geometric frustration in β-Mn, phase stability, and phase transitions In the preceding paper [D. Hobbs, J. Hafner, and D. Spiák, Phys. Rev. B 68, 014407 (2003)], we have started an ab initio spin-density-functional study of ... J...
Figures 5 and 6 illustrate the effects of element content on the GFAs of the binary Nb-Al and ternary Ni-Nb-Al alloy systems, respectively. The amorphous phase of the binary Nb-Al alloy formed in the composition range 10–90 at.% Nb (Figure 5), reasonably consistent with the GFR of ...
A Super-Element of Track-Wheel-Terrain Interaction for Dynamic Simulation of Tracked Vehicles A track-wheel-terrain interaction model is presented in this paper, which can be used as a "force" super-element in a multibody dynamics code for dynamic s... ZD Ma,NC Perkins - 《Multibody System...
Seals are a crucial machine element used to confine a high pressure fluid to some given volume. Due to the interfacial surface roughness most seals exhibit leakage [1, 2]. To minimize the leakage, seals are usually made from a soft material, such as rubber (with an elastic modulus of orde...
To directly compare compounds, usually expressed as μg/ml or μM, all CdS, ZnO or TiO2 concentrations were expressed in μg/cm2 of metal element used. Characterization of particles Characterization of particles was performed in RPMI 1640-serum free medium. Transmission electron microscope (TEM,...
