Learning Goal:
To use a shear stress strain curve to determine the
shear modulus and to solve for the unknown force
and deftection for a block subjected to shear
A metal biock is part of an industral motor mount, has dinensions di 3 cm, di 36 cni, and da 5 cm, and is made of a
material with the shear stress-etrain curve shown. Use this block to answer the following ouestions Note: the given ourve has a
shape similar to that tor a typical metal, but the curve has been drawn using straight ines, and the yield point has beon moved to
a higher strain than is typical, to make the graph easier to read.
A stress-strain curve for shear represents the
response of a material to pure shear. The vertical
axis is the shear stress T. This stress is the force
paralel to a plane divided by the area of that plane.
The horizontal axis is the shear strain y. The shear
strain is the change in the angle between two ines
that were originally perpendicular (Eoure 1.

As with tension and compression, the typical intial
response is linear elastic, so the stress and strain
are related by r Gy, where G is caled the shear
modulus of elasticity and y is measured in radiana
This is followed by a nonlinear strain hardening
region. After reaching ultimate shear stress, the
object deforms rapidly in a localized portion, leading
to fracture.
