Proportional Limit Stress
Proportional Limit - The greatest stress a material is capable of withstanding without deviation from a straight -line proportionality between stress and strain. If the force applied to the material is released the material will return to its original shape and size.

Yield Point Stress
Yield point - The point at which a sudden elongation takes place, while the load on the sample remains the same or actually drops. If the force applied to the material is released the material will not return to its original shape and size.

Ultimate or Tensile Stress
Ultimate Strength - The point at which the maximum load for a sample is achieved. Beyond this point, elongation of the sample continues but the force being exerted decreases.

Breaking/Rupture Stress
Breaking/Rupture Stress - The maximum amount of stress that can be applied before rupture occurs. The material fractures in the necking region where the material reduces in diameter as the material elongates.

Modulus of Elasticity
Modulus of Elasticity -A measure of a materials ability to regain its original dimensions after the removal of a load or force. The modulus is the slope of the straight line portion of the stress-strain diagram up to the proportional limit.

Modulus of Resilience
Modulus of Resilience -A measure of a materials ability to absorb energy up to the elastic limit. This modulus is represented by the area under the stress versus strain curve from zero force to the elastic limit.

Modulus of Toughness
Modulus of Toughness -A measure of a materials ability to plastically deform without fracturing. Work is performed by the material absorbing energy by the blow or deformation. This measurement is equal to the area under the stress versus strain curve from its origin through the rupture point.
