Contact strength of the GFRC was investigated theoretically and experimentally. The sizes of contact spot and indention of spherical and cylindrical body were defined by iterations repeating the procedure of finite element analysis. The use of the general and special criteria of destruction can give the sufficient information for the approximate prediction of kind of partial destructions in a material and the sizes of a zone of damage. Results of microscopic researches of a surface of a cut in a zone of impact confirm the described shape of destruction of fiberglass at impact with rather small energy.
