A cylindrical bar of radius 15 mm and length 100 mm is held at both ends. If at 30 °C no axial force exists in the bar, determine the stresses and strains in the bar when the temperature rises to 100 °C. Also determine the axial force and deformation of the diameter due to temperature rise. Let E = 120 GPa and Co-efficient of linear thermal expansion = 0.0000168 per °C.
What are effects of the annealing process on the density of these dislocations ? Can you give examples for materials?
