  2. Ultimate tensile strength - Wikipedia

    en.wikipedia.org/wiki/Ultimate_tensile_strength

    The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.

  3. Fatigue limit - Wikipedia

    en.wikipedia.org/wiki/Fatigue_limit

    Typical values of the limit for steels are one half the ultimate tensile strength, to a maximum of 290 MPa (42 ksi).For iron, aluminium, and copper alloys, is typically 0.4 times the ultimate tensile strength.

  4. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    The ultimate strength is the maximum stress that a material can withstand before it breaks or weakens. [12] For example, the ultimate tensile strength (UTS) of AISI 1018 Steel is 440 MPa. In Imperial units, the unit of stress is given as lbf/in 2 or pounds-force per square inch. This unit is often abbreviated as psi.

  5. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_curve

    This region starts as the stress goes beyond the yielding point, reaching a maximum at the ultimate strength point, which is the maximal stress that can be sustained and is called the ultimate tensile strength (UTS). In this region, the stress mainly increases as the material elongates, except that for some materials such as steel, there is a ...

  6. Steel grades - Wikipedia

    en.wikipedia.org/wiki/Steel_grades

    Steel for rail use: Minimum Yield Case: H: High Tensile Strength Flat products: Minimum Yield Case: If followed by T then the given mechanical property is minimum tensile strength D: Flat Products for Cold Forming: Followed by C, D or X and two numbers characterising steel T: Tinmill Products: Nominal Yield Case: M: Electrical Steel: Number ...

  7. Strain hardening exponent - Wikipedia

    en.wikipedia.org/wiki/Strain_hardening_exponent

    In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.

  9. Material failure theory - Wikipedia

    en.wikipedia.org/wiki/Material_failure_theory

    The maximum stress criterion assumes that a material fails when the maximum principal stress in a material element exceeds the uniaxial tensile strength of the material. Alternatively, the material will fail if the minimum principal stress σ 3 {\displaystyle \sigma _{3}} is less than the uniaxial compressive strength of the material.
