A Comparitive Study On Ceramic Powder Over Static And Dynamic Compaction

Shanmugam M. V., KARTHIKEYAN R., Divyakumar P., Nirmal Raja R.

Abstract


The unique microstructure of dense ceramic powders are studied with the help of both static and dynamic process. Initial density, particle size distribution, particle morphology, and loading path are the various effects that are investigated in the static experiments. . At very low velocity steady structured compaction waves are traveling in dynamic experiment. When compared with static response the ceramic powder are found to be significantly stiffer at dynamic response. Because, deformation is confined to the relatively narrow compaction wave front. Density and mechanical properties such as Vickers micro hardness and bending strength of the powder samples were investigated. The increase in impact force tends to decrease springback of the compaction.
