In solid mechanics, how does COMSOL calculate Bulk Modulus (solid.K)?
I am trying to calculate K for a composite material, using the typical formula Pressure/volumetric strain.
However, when i divide the the volumetric integration of the pressure by the volumetric integration of the volumetric strain, I cannot calculate the same result as how COMSOL calculates it.
My solution for a single material is correct.
Any thoughts?
