Thank you very much Dr. Martin Pieper. Yes phonon calculations speak about
stability of structure but not about breaking point.

Hello Muhammad!
A DFT code will not simply say *crack* at some point of strain. Wien2k
will always distribute the force you apply according to the perfect
translational symmetry of your crystal structure - in contrast to nature
where things like cracking or breaking occure at weak links -
