Mechanically alloyed (MA) alloys appear to be ideal candidates from which yield stress can be determined from hardness measurements. The yield stress of MA aluminum alloys can be represented by an equation of the form, 蟽 y=H/(3.0卤0.1), for a range of temperature/time conditions. It ...
A new plane stress yield function that well describes the anisotropic behavior of sheet metals, in particular, aluminum alloy sheets, was proposed. The anisotropy of the function was introduced in the formulation using two linear transformations on the Cauchy stress tensor. It was shown that the ...
The aim of this study was to explore the effect of the yield stress of the cracked thin panels of aluminum alloys panel, repaired with one sided fiber reinforced polymer (FRP) patch, on the performance of the repair. Various different grades of aluminum alloys with thickness in the range of...
Molecular dynamics (MD) and experimental data indicate that the stress at the yield point of uniaxially stretched nanowires suffers a sudden large drop (D). In addition, nanowires show a yield strength (YS) significantly higher than that of bulk material. In this work, aiming to identify the ...

The variation of the yield stress of pure lead in uniaxial compression with temperature, strain and strain-rate is described together with experiments designed to test the accuracy of the results. The average coefficient of friction between the platens and specimen has been measured for lubricated ...
dashpots such that the stress-strain rate relationship can be given as , where σ is the stress, η is the viscosity of the material, and dε/dt is the time derivative of strain. Since the analysis is very dependent on the model that is chosen, Nanovea provides the tool to gather ...
Yield criterions of metal plasticity in different stress states Five types of tensile tests were conducted to study the yield behavior of 2A12-T4 aluminum alloy.Parallel finite element models were built for each test an... Fengping,YANG,1),... - 《Acta Metallurgica Sinica》 被引量: 7发表:...
The Hill-48 yield criterion is a special case of the damage ratio strength theory for orthotropic metals under uniaxial and biaxial tensile stress states. The proposed yield theory is confirmed by the experimental yield stresses of magnesium alloy, aluminum alloy, steel, zirconium, and IC10 alloy...
