    2/02/2010  Re: Compressive Yield vs. Compressive Strength for Iron 11/16/2006 8:59 AM Careful, Iron is a brittle metal, there's very minimal plastic deformation and/or elasticity, but there is some, and yes, that's accurate about yield point.

  • Compressive strength - Wikipedia

    Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials ...

  • Gray iron - Wikipedia

    Gray iron, or grey cast iron, is a type of cast iron that has a graphitic microstructure. It is named after the gray color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material based on weight. It is used for housings where the stiffness of the component is more important than its tensile strength, such as ...

  • Compressive strength of rocks - PetroWiki

    Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

  • Corrosionpedia - What is a Compressive Strength ...

    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).
