Subject Code: 22035


  • Determine stress strain relations for steel.
  • Determine hardness of materials.
  • Perform torsion, bending, impact and shear tests.


  1. Test on Ductile Materials: Finding Young’s Modulus of Elasticity, yield points, percentage elongation and percentage reduction in area, stress strain diagram plotting, tests on mild steel.
  2. Hardness Test:Determination of Rockwell’s Hardness Number for various materials like mild steel, high carbon steel, brass, copper and aluminium.
  3. Torsion test: Torsion test on mild steel – relation between torque and angle of twist-determination of shear modulus and shear stress.
  4. Bending and deflection tests: Determination of Young’s Modulus for steel by deflection test.
  5. Impact test: Finding the resistance of materials to impact loads by Izod test and Charpy test.
  6. Tests on springs of circular section: Determination of modulus of rigidity, strain energy, shear stress and stiffness by load deflection method (Open & Closed coil spring)
  7. Shear test: Single or double Shear test on M.S. bar to finding the resistance of material to shear load.
