Property of Materials
Stress-strain curve

Zone 1 - Area of Elasticity
Young's modulus
Stress/Strain in elastic zone.
Measures stiffness of material.
Higher the Young's modulus, steeper the slope + higher the stiffness.
what happens after proportional limit ?
after this material elongates.
what is ultimate strength ?
it is the point of maximum stress. Stress gradually reduces as strain increases.
what happens after fracture point?
material fails. Area under the curve is energy of failure.
what is plastic zone ?
material does not regain its original length when load applied.
