Graphs
Yield point
The point at which the material stops behaving elastically - usually a little bump in the graph's line

-
Elastic deformation
constant gradient, first part of the graph, before yield point
Plastic deformation
changing gradient, past yield point

Properties
Metals
Ductile due to high amount of mobile dislocations (extra half-planes of atoms) meaning it takes much less energy to move layers of atoms past each other
Resistant to crack propagation due to their ductility as the high-stress area at the base of the crack stretches and increases in area, decreasing stress.
