You should consider the implicances of your question, which is mostly a philosophical issue regarding our human subjectivity. You are implying an ideal uniformity of states which wouldn't allow quantum behavior.
That would mean that atoms should have all the exact same state before the breaking, that is, considering them as particles, they should be all at the same angle, have the same rotational speed, same energy, etc. In such case, the momentum of the expansion process would be exactly the same for all couples, and the object would dissipate perfectly as smoke.
A very beautiful and utopic idea. But reality is not like that. Things might break even without stressing them. The probability of a body to remain intact without external action is not 100%.
Taking such logic to the extreme, it means that even if the material is perfect, all its couples of structural interactions have different degrees of resistance to stress... That means that absolutely all couples have different values, even if they are infinitesimally small!
