NUMEROUS investigations of the factors controlling the lower yield point have shown that the lower yield point (σ LYP) varies with grain size (d) according to the equation: ...
Most metals when stressed, after a certain elastic deformation, undergo a permanent elongation starting at the ‘yield point’. In some materials, the stress then falls to a lower value; an ‘upper yield ...
