That is because the lateral deformation is less than 1 mm (shearing strain [gamma] < 2%) in the test, and the actual shear modulus is much larger than theoretical value ([gamma] = 100%) when [gamma] is minimal.
Based on the shearing strain 100% (50 mm), the variation range of [K.sub.h1] will be 0.93-1.08.
is the vector of normal and shearing strains. In Eq.
The shearing forces directly calculated from the shearing strains (Eq.
In order to reduce this shearing strain
to a minimum, Konig developed the TwinSat which has two satellite multi-roller heads arranged one above the other.
Thanks to this processing technique the TwinSat achieves a dough free from shearing strain
. The gas pores are preserved giving excellent proofing volume.

The quantity Gmax, sometimes also called the rigidity, which is experimentally observed to relate stress and strain according to Hooke's law can also be explained as, a measure of the resistance of the body to shearing strains
