Generally, the chip consists of series of plate elements of thickness At and it is displaced through a distance AS relative to each other as shown in Figure 1.20.

SHEAR STRAIN

Generally, the chip consists of series of plate elements of thickness At and it is displaced through a distance AS relative to each other as shown in Figure 1.20.

It is known that the strain is defined as the deformation per unit length.


Substituting tan β value in equation (1.4),


Multiplying and dividing the second term by cosα,
