Ceramic deformation behavior under compression.

While ceramic powder exhibits special densification behavior during compression. Therefore debate continues on the dynamic deformation behavior and the underlying micromechanisms even for the same ceramic with different fabrication processes. The results of this work indicate a significant difference between the density dependence in tension and compression. A generalized confined compression test cct was simulated in the present study to investigate the deformation of walnut ceramic proppants against compression.

The stress strain behavior of the four metals under compression is shown. This study is an attempt to investigate the mechanical behavior of proppant packs deforming under compression loading. The densification mechanism of ceramic particles under high pressure sintering starts with plastic period following by grain boundary sliding and diffusion as is reported in refs. The difference in deformation behavior between homogeneous pillars and multilayer pillars along with other geometric effects were examined in detail.

Covalent bonds of a ceramic will resist deformation when a force is applied but break when the threshold is passed whereas the delocalized nature of the bonds in metals allows for plastic deformation or ductile behavior. In this way the cct was simulated. Materials and methods 2 2 uniaxial tension.
