Elastic and plastic behaviour
What this topic asks you to be able to do
- understand the meaning of, and be able to apply, the terms elastic deformation, plastic deformation and elastic limit
- understand that the work done is given by the area beneath the force–extension graph
- find the elastic potential energy stored in a material whose deformation stays within its limit of proportionality, using the area under its force–extension graph
- recall EP = 1/2 Fx = 1/2 kx² and use it for a material's deformation up to its limit of proportionality
