In paper the numerical modeling of fragmentation of a thick-walled cylindrical copper shell under an effect of a detonation products of explosive is held. The problem was considered in a planar two-dimensional formulation. At the solution of a problem the random character of initial defects distribution of a material structure was allowed. Therefore initial damages in a material are modeling by variation of a yield point, which is submitting to a normal distribution law with a mean arithmetical, equal tabulated value and varied dispersion.
