Abstract
It is shown how the macroscopic structure of material affect the mechanical strength of glass foam as well as the quantity and the size of a crystalline material pre-senting in the noncrystalline matrix of the interpore partition. It has been stated that the material having a hex-agonal form of pores of 1-1, 5 mm in size and 40-50 μm in thickness of partitions, possesses maximum strength. In forming nanospheroids in the noncrystalline matrix of the foamed material partition, its strength reaches 4, 5 MPa that approaches to calculate strength values (5 MPa). In this paper, the degradation mechanism is de-scribed for foamed material using the equations of a synergetic model of amorphous body deformation.
