Have students provide examples of materials that fit each description: Elastic ... pressure, deformation rate, and material composition are important. Caution: Crustal rocks may exhibit ductile ...

E is an elastic constant, Young's modulus. A material exhibiting this behavior over the complete range of elastic deformation is known as a linear elastic material. Some materials have a non-linear ...

Push an object's ends together, eg when an empty drinks can is squashed. A rubber band undergoes elastic deformation when stretched a little. A metal drinks can undergoes inelastic deformation ...
