Mechanical Testing & Quality Control Practical

Subject Code: 22035

A. MECHANICAL TESTING

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

Exercises

  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.

B. QUALITY CONTROL

  • To study the microscope structure of the metals
  • Determine the microscope structure of the ferrous and nonferrous metals
  • Conduct the liquid penetration test to find crack
  • Conduct magnetic particle test to find cracks

Exercise

  1. Using the Metallurgical microscope and identify the grain structure of given specimen.
  2. Preparation of specimen to examine the micro structure of metal samples (i)Ferrous and (ii) Non-Ferrous (Minimum two exercises on each category).
  3. Detection of Cracks in casting using Visual Inspection and ring test&Die penetrant test
  4. Detection of Cracks in casting using Magnetic particle test.
