Hii all..
I have a question.Suppose there is a cube of side 1m .It is heated by 1°C. The cube is not restrained in any direction. We are required to find out the volumetric strain.
I am getting it as 3α.
But my question is that since the cube is not restrained , ∴ there should be no stresses in any direction.
∴ εv=(σx +σy+σz)(1-2μ)/E
which gives εv=0.
please help..
