Importantly, the yield stress of the fluid when in its active ( " on " ) state can be controlled very accurately by varying the magnetic field intensity.
32.
Another reason is that the crease locally hard works the steel, raising its yield stress in that area, and making it a bit more resistant to denting.
33.
In more laymen's terms, the yield stress is the tipping point for conformational change in the mayonnaise after initial force is applied and it is held constant.
34.
Thus, less force need be applied to move a dislocation from a larger, than from a smaller grain, leading materials with smaller grains to exhibit higher yield stress.
35.
Thus you will have to apply less force to move a dislocation from a larger than from a smaller grain, leading materials with smaller grains to exhibit higher yield stress.
36.
Surfactants are typically used to offset this effect, but at a cost of the fluid's magnetic saturation, and thus the maximum yield stress exhibited in its activated state.
37.
As for the largest cube, I think diamond would be in the running ( yield stress 35 GPa ) and should get you up to about 7000 km in side length.
38.
Where \ sigma _ y is the yield stress, G is the shear elastic modulus, b is the magnitude of the Burgers vector, and \ rho is the dislocation density.
39.
The elastic response of viscoplastic materials can be represented in one-dimension by yield stress ( ? y ) that is strain rate dependent, or even constant, as shown in Figure 1c.
40.
It provides tables for the design stress values, tensile and yield stress values as well as tables for material properties ( Modulus of Elasticity, Coefficient of heat transfer " et al . ")
