Ceramic Deformation Behavior Under Compression

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.

Ceramic deformation behavior under compression.

Implying an elastic deformation process under cold compression. The objective of this research is to explore the deformation behavior and fracture process of the sic under uniaxial impact loads. 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. This study is an attempt to investigate the mechanical behavior of proppant packs deforming under compression loading.

While ceramic powder exhibits special densification behavior during compression. In this way the cct was simulated. Materials and methods 2 2 uniaxial tension. 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 model assumes that identical deformation modes bending failure of the struts are responsible for failure of the bulk foam in tension and compression. The difference in deformation behavior between homogeneous pillars and multilayer pillars along with other geometric effects were examined in detail.
