Shear
From Soft-Matter
To shear something is to cause a shear strain, by application of a shear stress. Recall that the shear stress σ is given by the applied force F over the area A, namely
<math>\sigma = \frac{F}{A}</math> ,
and the shear strain e is given by
<math>e = \frac{\Delta x}{y}</math> .
See Figure 1 for clarification.
