Elements Of Solid Mechanics Laboratory
Lab-in-charge: Dr. Ranjan Basak
In this laboratory, students will have the opportunity to apply loads to various materials
under different equilibrium conditions. The student will perform tests on materials in
tension, compression, torsion, bending, and impact. These conditions and/or constraints
are designed to reinforce classroom theory by having the student perform required tests,
analyse subsequent data, and present the results in a professionally prepared report. The
machines and equipment used to determine experimental data include universal testing
machines, torsion equipment, spring testing machine, compression testing machine,
impact tester, hardness tester, etc. Data will be collected using Dial indicators,
extensometers, strain gages and strain indicator equipment, as well as load and strain
readouts on the machinery and graphing capabilities to print relevant plots for analysis.
This course will advance the students' development of the following broad capabilities:
Students will be able to understand basic concepts of stress, strain and their
relations based on linear elasticity. Material behaviours due to different types of
loading will be discussed.
Students will be able to understand and know how to calculate stresses and
deformation of a bar due to an axial loading under uniform and non-uniform
Students will understand how to develop shear-moment diagrams of a beam and
find the Maximum moment/shear and their locations
Students will understand how to calculate normal and shear stresses
Upon completion of this laboratory course, students will be able to
