  2. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    Compressive strength is a limit state of compressive stress that leads to failure in a material in the manner of ductile failure (infinite theoretical yield) or brittle failure (rupture as the result of crack propagation, or sliding along a weak plane – see shear strength). Tensile strength or ultimate tensile strength is a limit state of ...

  3. Compressive strength - Wikipedia

    en.wikipedia.org/wiki/Compressive_strength

    Measuring the compressive strength of a steel drum. In mechanics, compressive strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength which withstands loads tending to elongate, resisting tension (being pulled apart).

  4. Work hardening - Wikipedia

    en.wikipedia.org/wiki/Work_hardening

    Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [ 1 ]

  5. Yield (engineering) - Wikipedia

    en.wikipedia.org/wiki/Yield_(engineering)

    The yield strength or yield stress is a material property and is the stress corresponding to the yield point at which the material begins to deform plastically. The yield strength is often used to determine the maximum allowable load in a mechanical component, since it represents the upper limit to forces that can be applied without producing ...

  6. Bauschinger effect - Wikipedia

    en.wikipedia.org/wiki/Bauschinger_effect

    While more tensile cold working increases the tensile yield strength, the local initial compressive yield strength after tensile cold working is actually reduced. The greater the tensile cold working, the lower the compressive yield strength. It is a general phenomenon found in most polycrystalline metals. Based on the cold work structure, two ...

  7. 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.

  8. Stress–strain curve - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_curve

    A typical stress–strain curve for a brittle material will be linear. For some materials, such as concrete, tensile strength is negligible compared to the compressive strength and it is assumed to be zero for many engineering applications. Glass fibers have a tensile strength greater than

  9. Strengthening mechanisms of materials - Wikipedia

    en.wikipedia.org/wiki/Strengthening_mechanisms...

    Tensile strengths of TRIP steels are in the range of 600-960 MPa. Martensitic steels are also high in C and Mn. These are fully quenched to martensite during processing. The martensite structure is then tempered back to the appropriate strength level, adding toughness to the steel. Tensile strengths for these steels range as high as 1500 MPa.
