  • What Is Bulk Modulus? Definition, Formulas, Examples

    27/1/2019· Usually, bulk modulus is indicated by K or B in equations and tables. While it applies to uniform compression of any substance, it is most often used to describe the behavior of fluids. It can be used to predict compression, calculate density, and indirectly indicate the types of chemical bonding within a substance.

  • 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 being pushed together, whereas tensile strength resists tension (being pulled apart). In the
