The most general processing method used for the ceramic materials is grinding.
Focus on the machining feed rate to influence the grinding time, it shows that when machine the hard materials, machine tool hardness should be three times harder than the raw materials; however, high hardness cutting tools cannot promise cutting all the raw materials.

These materials were then poled and their
piezoelectric properties were measured.
SEM analysis indicated that the grain size within the materials decreased as the proportion of BT in the material was reduced.
No piezoelectric effect was found in materials containing less than 70% BT
The piezoelectric constant (d33) of these materials varies from 0pCN -1 at 70% BT to 108pCN -1 at 100% BT.

Electrochemical reaction occurring in the SOFC cathode is the reduction of oxygen, therefore cathode materials for SOFC have to posses many properties.
The-state-of-the-art cathode material, LSM-ScSZ composite material was used to investigate cathode degradation.

Preliminary Investigations on the Reduction of Foot Pressure Measurement and Muscle Activity with Different Insole Materials
A.
FEA was done to determine the force distribution under the foot using two different insole materials.
Dynamic loading pressure data collected and Table 1 shows the outcome measurement for four subjects using two different types of insole materials.
This can be associated with the mechanical properties of the both materials that have shock absorbing characteristic.
