Abstract

Mechanical tests of fragments of Chirona evermanni houses from the Sea of Okhotsk and Balanus eburneus houses attached to the stone substrate from the Barents Sea made it possible to determine the amount of effort required to destroy fragments of houses and whole houses attached to the substrate, as well as the strength and crack resistance of the shell material. The tests showed an almost tenfold spread of the destructive force. According to the level of crack resistance and the nature of destruction, the materials of the houses Chirona evermanni and Balanus eburneus turned out to be close to sedimentary rocks. The spread of values obtained during the experiment is determined by the topological and morphological features of the houses.
