Polymers such as polyurea are widely used ... In technical terms, the ‘elastic modulus’ – a measure of the force needed to deform a material – could be varied from 22 to 172 Megapascals ...

In the initial stage of strain, the response is linear in the stress and may be described by Hooke's law: s = E e. E is an elastic constant, Young's modulus. A material exhibiting this behavior over ...

Neither of these materials, however, shows significant amounts of elasticity ... polymer shows very interesting mechanical properties. It is a relatively strong material (Young's modulus of ...

elasticity, and resilience, you must not only consider the type of polymer, but also the mechanics of its macromolecular architecture. Sergei Sheiko of North Carolina at Chapel Hill will first delve ...
