Stress vs strain curve | Class 11 (India) | Physics | Khan Academy

What happens if you stretch something beyond its elastic limits?

In this video, we will explore the regions beyond the elastic limits. We will take a steel rod and keep stressing it until it breaks. We will draw a graph of stress vs strain and explore all the different regions of it.

This is an amazing video! It never made sense to me why after max stress that the strain would increase as the stress decreased but that was a perfect explanation.
