To compare the results between elastic and hyperelastic model, a 3-D finite element numerical model developed based on two different materials of elastic and hyperelastic material properties.
For use in elastography, the tissue mimicking materials must exhibit the same material properties as that of the tissue being mimicked.
Gelatin materials suffer from several drawbacks.
The analysis involved employing ABAQUS as a solver including two different materials, Elastic and hyperelastic based on experimental data.

Introduction Vibration and impact are the most common external excitation in packaging system, the amount of energy absorbed by the packaging materials, when the packaged product reach its ultimate bearing strength , is an important index in packaging evaluation, the bigger the better.
Suppose the mass of an electronic product is m = 6 kg, and the contact area between the packaging materials and it is 0.05 m2.

The selection of these materials allows to obtain a high corrosion resistance electrolytic pair, by replacing the high cost platinum electrode usually employed in the alkaline electrolysis process.
There are several materials that can be used as electrodes in alkaline electrolysis.
Platinum and gold are technically the most suitable materials to be used as electrodes.
Materials and Methods Reactor Project The objective of the electrolytic reactor project is to maximize the contact area of the electrodes with the electrolyte.
