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...
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 ...
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 ...
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 ...
For elastic solids numerical contact mechanics models [9], such as the boundary element model, and the analytic theory of Persson [10, 11], can be used to calculate the surface separation at the critical junction and hence predict fluid leakage rates. For solids exhibiting plastic flow, the ...
The schematic diagram of the pipe excitation method approach is shown in Figure9. This method is applicable to the case that the buried non-metallic pipeline can be touched from the surface (such as the surge tank) [17]. The basic principle of the pipe excitation method [62,63] is to ...
element I1, as indicated in dotted lines in Fig. 2, and to bring its first mitre - notch B to the bending station, the angulating element II will be actuated to the position Ila to bend the strip at the first tie 14 and angulate the frame section a in relation to the frame ...
The activation energy for electron exchange between sites in the latter systems disappears if the intermetal coupling matrix element is larger than twice E 0, where E 0 is the activation energy for vanishing intermetal coupling. In the case of CuO the intermetal coupling is unusually large since ...
A study on the structure and electrochemical properties of La2Mg(Ni0.95M0.05)9 (M = Co, Mn, Fe, Al, Cu, Sn) hydrogen storage electrode alloys The effect of replacing part of the Ni by a metallic element in La 2MgNi 9 on the structure and electrochemical properties of the thus formed...
