“We classify deformations by whether the object returns to its original shape after the force is removed. In an elastic deformation, the object returns to its original shape. The deformation is plastic if the object keeps its new shape, even after the deforming force is removed. If a large enough force is applied to any object, the deformations will be plastic. For example, an elastic band can only be stretched so far before it breaks. The elastic limit is the transition point between elastic and plastic deformations of materials.
Here is an animation demonstrating a material being stretched with increasing forces until it reaches its elastic limit, at which point it is permanently deformed.”
And yes- I am thinking about my pregnancy while reading this. I didn’t watch the animation. Couldn’t bear it.
