Atomic structure changes of a crystal induced by shock waves are studied by molecular dynamic method. α‐Fe crystallites are used for simulation having a rectangular area in the (110) plane and containing about 10 4 atoms. The radial distribution function of atoms is shown to lose its discrete form, typical of a crystal and to become continuous when the shock wave planar front is distorted. Microfragmentation in the corresponding areas of a crystal is shown at the same time to be the result of the shock wave distortion with a planar front.
