B.E. (Automobile Engineering) Material Testing Lab Syllabus - Mumbai University 2026

Lab Objectives

• 1 To familiarize students with examination techniques of microstructure in ferrous and or non ferrous metals to make them understand a correlation between microstructure and mechanical properties.
• 2 To introduce students to fundamentals of testing methods used to evaluate the mechanical properties of engineering materials.
• 3 To familiarize the students about fatigue test and S-N curve.
• 4 To introduce to the students simple tension test to analyze the stress - strain behavior of materials
• 5 To develop hands-on skills in students in conducting standard material tests such as impact, hardness, torsion, and compression.
• 6 To cultivate the ability in students to interpret and analyze test results in relation to properties and behavior of materials under different loading conditions. Lab Outcomes: After completion of this laboratory course, the students will be able to
• 1 Prepare metallic samples for studying its microstructure following the appropriate procedure.
• 2 Identify effects of heat treatment on microstructure of medium carbon steel and hardenability of steel using Jominy end quench test.
• 3 Perform fatigue test and draw S-N curve.
• 4 Perform simple tension test to analyze the stress - strain behavior of materials.
• 5 Measure torsional strength, hardness and impact resistance of the material.
• 6 Perform flexural test with central and three-point loading conditions. Page | 28 A. List of Experiments: Minimum eight experiments to be performed ( Four Experiments each from both the groups) Expt. Description No. No. of Hou rs Group A
