SUMMARY
The Birch-Murnaghan equation, essential for modeling volume behavior under high pressures exceeding 1 GPa, is derived from principles outlined in Birch's 1947 paper, “Finite Elastic Strain of Cubic Crystals,” published in Physical Review. Key parameters include Vo, the volume at ambient pressure, Bo, the bulk modulus, and B’, its pressure derivative. The derivation is isothermal, and additional resources, such as the PDF found at https://mcbrennan.github.io/BMderivation.pdf, provide further insights into the mathematical formulation.
