  • 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.

    CalculationS = F / AGraph

    Stress (S) psi

    Strain (() in/in

  • 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.

    CalculationS = F / AGraph

    Yield Point

    Stress (S) psi

    Strain (() in/in

  • 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.

    CalculationS = F / AGraph

    Ultimate Strength

    Stress (S) psi

    Strain (() in/in

  • 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.

    CalculationS = F / AGraph

    Rupture Point

    Necking Region

    Stress (S) psi

    Strain (() in/in

  • 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.

    CalculationE = (F1 -F2)Lo / (1 - 2)AGraph

    Proportional / Elastic Limit

    Slope

    Strain (() in/in

  • 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.

    CalculationUr = 1/2 (yp)( yp)Graph

    Elastic Region

    Stress (S) psi

    Strain (() in/in

  • 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.

    Calculation:

    Ut = 1/3(Br) (yp + 2ult)

  • Calculation PageTotal Strain/ Deformation -The total amount of elongation of a sample to rupture normalized(divided by) by the initial length.Calculation:total = total/LoDuctility:The ability of a material to be deformed plastically without rupture.Calculation: % Elongation = total(100)Ductility:The ability of a material to be deformed plastically without rupture.Calculations: % Reduction in area = Aoriginal - A final / A original (100)
