However, if one takes the point of view that a fluid is a body that cannot sustain shear, then by definition there can be no “shear stress threshold” to the flow, which is the basic premise of the notion of a “yield stress”. This is yet another example where the importance of ...
The strength and dependability of these vehicles are greatly improved with the use of spot welds [1]. Vehicles are also exposed to environments containing salt, such as de-icing salt on roads or salt in the air near saltwater bodies. The presence of salt can then affect the undercarriage or...
It was shown in [6] that prior static deformation of sheet aluminum alloy 6061 by 2.5-3% led to a reduction in the criterial stress level by 20-30%, corresponding to initiation of damage in the material with a typical size of ~ 1 ~m. At the same time for sheet and bar materials ...

Evolution of subsequent yield surfaces and elastic constants with finite plastic deformation, Part-II: a very high work hardening aluminum alloy (annealed 1100 Al). Int. J. Plast., accepted for publication; Khan, A.S., Pandey, A., Stoughton, T., 2009b. Evolution of subsequent yield ...
Aluminum alloy in the peak-aged state mainly contains β” and β’ precipitates. Most of the literature has only considered the strengthening effect of β”. Here, we develop a single-crystal intensity model including both precipitate enhancement effects for the first time. This model was ...
The initial composition of the metastable solid solution is calculated using the point calculation function of PanEngine. It is assumed that the maximum solubility of elements is achieved at the end of the solution heat treatment. α-Al15(Fe,Mn)3Si2 phase, which is a common phase constituent ...
