Strength Of Materials

This NPTEL course from IIT Madras and IIT Guwahati starts from the stress vector and builds toward the full picture of how materials deform under load. Its opening lectures introduce the stress tensor and the equilibrium conditions that every later result depends on.

Stress, then strain

Mohr's circle, its proof, and the principal stresses form the core of the stress half of the course. The strain half covers the state of strain, how it is measured, and the tension test, which ties the theory back to a physical experiment.

Points worth knowing before you start

• The course treats stress as a tensor, so vector and matrix thinking help from the first lecture.
• Photoelasticity appears as a measurement technique, giving a visual route into stress patterns.
• The listing ends at the tension test, so check the course page for the sections that follow it.
