Materials: Force - Extension Graph QueryWatch this thread
My question is:
Why don't we get plastic deformation during the stage between these 2 and is the gradient of this region the same as when Hooke's law was being obeyed? I think my textbook just doesn't have a clear enough diagram as from what I know it makes sense for it to start curving once the limit of proportionality has been reached.
Thanks in advance for any replies!
It just depends on the material. For example, an elastic band has no linear regions at all, but has elastic behaviour. Brittle objects may follow Hooke's law up until breaking point.
P.S. I don't think brittle materials don't follow Hooke's Law lel
