Finite strain theory

Finite strain theory is a way of understanding how objects may change shape (or strain) when they are put under different forces, like when you squeeze a rubber band or stretch a piece of play dough. It helps engineers figure out how different materials will respond when certain forces are applied, so they can make sure that the things they build are strong and safe.

Finite strain theory works by looking at how much an object changes shape when force is put on it. If the shape changes a lot, then the object is said to have a lot of strain. On the other hand, if the shape doesn't change much, then the object is said to have little strain. Engineers can use this information to figure out which materials are best for different kinds of projects.
