The non-hooke's behavior of porous zirconia subjected to high-rate compressive deformation

Abstract

The deformation of partially stabilized zirconia ZrO₂(Y₂O₃) with various pore morphologies is studied. During the synthesis of bar and lamellar ceramic structures, an effect of mechanical instability is discovered. This effect, along with the purely elastic behavior of the ceramic and the accumulation of microdamages under high-rate compressive deformation, produces considerable strains in the porous structure without material failure and substantially extends the applications of porous ceramic materials.
