Stress and strain are two terms that often get thrown around interchangeably, but in the world of materials science and engineering, they have very distinct meanings. So let’s break it down in a way that even your grandma can understand.
Imagine you’re walking down the street, minding your own business, when suddenly a giant piano falls out of the sky and lands right in front of you. The stress you feel in that moment is the force per unit area that the piano exerts on your poor, unsuspecting body. Ouch.
Now, let’s say you manage to somehow hold up the piano with all your might (maybe you’ve been hitting the gym lately). The strain you experience is the change in shape or size of your body as a result of the applied stress. In this case, probably a lot of squishing and squashing.
But how do stress and strain relate to each other? Well, it’s like the best buddy cop duo you’ve ever seen. Stress is the tough guy who dishes out the punishment, while strain is the one who takes the beating and shows the battle scars. They work together to give you a full picture of how a material responds to external forces.
