How to find yield strength and Young Modulus from S-S curve

http://pipeng.com/index.php/ts/itdmotdiam008l Proof stress is determined as the stress corresponding to 0.2% of strain from the stress-strain curve of the given material. This is the stress value determined for the materials like aluminum, magnesium and copper whose yield point cannot be easily defined.
