Mechanical behavior of porous zirconium dioxide under active deformation by compression

Abstract

The properties of the mechanical behavior of porous ceramic based on partially stabilized zirconium dioxide are studied. The special features of the mechanical behavior of ceramic with different degrees of porosity are determined. It is shown that three macrodeformation mechanisms are observed simultaneously in the material: elastic deformation characteristic of compact material; microcracking with accumulation of microdefects; and displacement of local volumes of material into the pore space. A ceramic with porosity less than 20% retains its capacity for transformational changes in the stress field of a propagating crack.
