Mechanical Deformation of Porous Ceramics
Introduction PZT95/5 is the ceramic used in the experiment and is ferroelectric at room temperature. Ceramics generally have low tensile strength and fracture toughness which is the reason for dielectric breakdown under shock wave compression. Porous ceramics exhibit greater resistance to dielectric breakdown under shockwave compression due to presence of voids.
Sample and Impact Setup For the sample high purity oxide powders are combined with PMMA pore formers to create porous PZT95/5 ceramics. Impact Plate Setup:
Observations After giving shock waves to PZT95/5 ceramic it can concluded that shock wave compression can be divided into four stages:
Observations Influence of Porosity: Influence of Impact Velocity:
