Calculates the bulk modulus (K) from two of the three other elastic moduli: Young's modulus (E), shear modulus (G), or Poisson's ratio (\(\nu\)). Assumes 3D material properties.
The relationships used are: $$K = \frac{E G}{3(3G - E)}$$ $$K = \frac{2G(1 + \nu)}{3(1 - 2\nu)}$$ $$K = \frac{E}{3(1 - 2\nu)}$$
