Generally, most materials experience elastic deformation followed by some plastic deformation until they fail. However, there are certain materials that don't follow this pattern. Such materials experience very large elastic deformation before they fail.
For instance, when we wear latex gloves, they stretch and remain pressed on to our hands. When we remove the gloves we notice that they haven't sustained any permanent damage despite stretching.
Even our muscle tissues can stretch without sustaining damage as long as we're not injuring ourselves.
In this lesson, we will introduce hyperelasticity and provide some examples of materials that have such characteristics.
Here are the accompanying handout slides for this lesson.
