STRENGTH OF MATERIALS LAB

Lab Incharge: Dr Sumit Joshi

Lab Technician: Mr Surender Singh

The Strength of Materials-I Lab is designed to provide students with hands-on experience in testing mechanical properties of engineering materials needed to design and manufacture machine elements.

The Strength of Materials-II Lab is offered as a program elective course in the 7th semester for Mechanical Engineering students. This lab provides hands-on experience in analyzing material failure mechanisms under various loading conditions. Additionally, students assess different mechanical properties through a series of experiments.

 

Lab Overview:

The lab is equipped with various instruments to measure mechanical properties like tensile strength, compressive strength, impact strength, hardness etc. that help students to understand fundamentals of design and application of materials in manufacturing machine elements.

Key Equipment in the Lab:

1. Universal Testing Machine – Used to measure tensile strength, compressive strength and shearing strength of materials.

2. Torsion Testing Machine – Used to measure shearing strength of material when subjected to torque

3. Brinell Hardness Testing Machine – Used to measure hardness of material with coarse grain structure

4. Rockwell Hardness Testing Machine – Used to measure hardness of material with fine grain structure

5. Impact Testing Machines – Izod and Charpy impact testing machine are used to measure the impact strength of material

6. Flexural Testing Machine- To Check the flexural strength of materials.

7. Buckling of Columns Apparatus - To check the buckling strength of structures.

8. Fatigue Testing Machine- To check the fatigue strength of materials.

9. Strain gauge apparatus- To measure the strain or deformation of an object under external forces

10. Deflection of beams apparatus- To verify experimentally the principal of beam deflection

11. Creep Apparatus- Used to study how materials deform over time under a constant load or stress

Learning Objectives:

After the completion of the course, the student will be able to

  1. Demonstrate the behavior and failure modes of materials under tension, compression, torsion, and deflection loads.

  2. Analyze the impact resistance, endurance strength, and shear strength of engineering materials.

  3. Differentiate among various hardness testing techniques and interpret their outcomes.

  4. Verify fundamental concepts such as Maxwell’s reciprocal theorem and evaluate the effects of different end conditions in columns.

  5. Demonstrate the working principle and applications of strain gauges and understand the creep behavior of materials.

  6. Compute mechanical properties and evaluate the flexural strength of structural elements like concrete beams.

This lab plays a crucial role in developing competency in engineering, preparing students for careers in manufacturing and product design.
