SUMMARY
The discussion centers on calculating the dilatation of a rock that is 60% porous when subjected to significant pressure. The user proposes that if the rock shrinks by 50%, the dilatation can be calculated using the formula ΔV/Vo = εxx + εyy + εzz, resulting in a dilatation value of 0.936. However, for large deformations, it is more accurate to express dilatation as ΔlnV, yielding a value of ln(0.4) = -0.916. This highlights the importance of using the correct mathematical approach for different deformation scenarios.
