A typical stress-strain curve showing the linear region, necking and eventual break. Shear strain is defined as the tangent of the angle theta, and, in essence, determines to what extent the plane was displaced. In this case, the force is applied as a couple (that is, not along the same line), tending to shear off the solid object that separates
