Sumario:Заглавие с титульного экрана
This work investigates the behavior of porous alumina (within the porosity range of 18% to 70%) ceramics when subjected to deformation by compression and shearing. The analysis of straindeformation curves showed that there was a transition from a typically brittle state for relatively dense ceramics, to a pseudo-plastic one with a high rate of porosity. The values of the effective elasticity modulus, effective shear modulus and Poisson's ratio decrease with an increase in volume in the pore space of ceramics, which correlates with the appearance of plural cracking during the deformation of ceramics with a high level of porosity.
