The problem of destruction of solid bodies is investigated by the scie
nce of strength of materials and constructions - mechanics of destruct
ion, expounded on the base of modern conceptions about destruction of
different nature bodies. Two kinds of material obtained in different w
ays have been investigated in this work. A method of alloying the micr
opowder composition by ultradispersed admixture was used. It increased
a value of the Veibull parameter and of average strength of these mat
erials. All these results were calculated and presented in diagrams.
