Mechanical property predictions for polymorphs of sulphathiazole and carbamazepine.

The mechanical properties of polymorphs of sulphathiazole and carbamazepine have been determined experimentally by three-point beam bending. It is shown that the mechanical properties of sulphathiazole and carbamazepine polymorphs can be predicted using the atom-atom potential model applied to lattice dynamics, as long as account is taken of crystal morphology when considering the experimental results.
