Hi,
About elastic and plastic materials:
All materials exhibit elastic deformation up to a certain limit, beyond which they exhibit plastic deformation.
Some materials, such as plasticine, have extremely tiny elastic regions, so we call them 'plastic materials'.
Some, like rubber, have large elastic regions, so we call them 'elastic materials'.
For some materials, within their elastic region, the force is directly proportional to the extension, and we say that these materials obey Hooke's Law.
Is that right? Or is it that plastic materials have no elastic region?
Would much appreciate your help :)
