  2. Rockwell hardness test - Wikipedia

    en.wikipedia.org/wiki/Rockwell_hardness_test

    The B and C scales overlap, such that readings below HRC 20 and those above HRB 100, generally considered unreliable, need not be taken or specified. Typical values include: Very hard steel (e.g. chisels, quality knife blades ): HRC 55–66 (Hardened High Speed Carbon and Tool Steels such as M2, W2, O1, CPM-M4, and D2, as well as many of the ...

  3. Stress–strength analysis - Wikipedia

    en.wikipedia.org/wiki/Stress–strength_analysis

    The area where the margin m = R - S is positive is the set of situation where the system is reliable (R > S). Stress–strength analysis is the analysis of the strength of the materials and the interference of the stresses placed on the materials, where "materials" is not necessarily the raw goods or parts, but can be an entire system.

  4. Crack spacing of reinforced concrete - Wikipedia

    en.wikipedia.org/wiki/Crack_spacing_of...

    Primary cracks (Figure 1) form when the tensile stress at the outer surface of the concrete reaches the tensile strength of concrete. When a primary crack forms, the concrete in the vicinity of the crack is relieved of any tension, resulting in a stress free zone near the crack. [1]

  5. Properties of concrete - Wikipedia

    Twenty eight days is a long wait to determine if desired strengths are going to be obtained, so three-day and seven-day strengths can be useful to predict the ultimate 28-day compressive strength of the concrete. A 25% strength gain between 7 and 28 days is often observed with 100% OPC (ordinary Portland cement) mixtures, and between 25% and 40 ...

  6. Strength of materials - Wikipedia

    en.wikipedia.org/wiki/Strength_of_materials

    The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...

    And further in AS3850, "The strength limit state capacity shall be determined by a statistical analysis from the test results in accordance with Paragraph A4.5." and assuming the test data is taken from a statistically valid test method , the data is to be determined via statistical means to derive the Load resistance model , for the anchor.
