Determine shear and normal stress directions
Webshear vanishes. Such stress components are very important since they turn out to be the maximum and minimum normal components, and so we give them a special name: … Webτ(θ) at one of these planes. The normal stress on all those four planes is equal to σm; these normal stress may be positive, negative or zero. This square with four faces …

When stress paths only are plotted then the axes of the diagram are really particular values of the shear stress τ and normal stress σ. These values are commonly referred to as q and p where q = τmax = σ1 - σ3 2 (7.4) p = mean normal stress = σ1 + σ3 2 (7.5)
