Modified Biot Elastic Coefficients in Poroelastic Solid.

An editorial focuses on refining Biot elastic coefficients in poroelastic solids by addressing discrepancies between drained and undrained conditions. It proposes new formulas for these coefficients and evaluates their accuracy through numerical analysis of Berea sandstone under different conditions. It highlights theoretical corrections needed for accurate wave propagation modeling in fluid-saturated porous media.
