Material of structure An important consideration of both the design and manufacturing process is the material used to build the individual components of the model Apollo Capsule.
Some materials are more difficult to drill and bore with such detail than others.
Providing a channel for electrical wires and pressure tapping tubes, easy access to electrode setup and using materials which have a high resistance to heat from sparking as well as pressures from the oncoming flow are just a few hurdles to overcome and the design has to be easily manufactured to avoid extreme costs.

Especially, after the vibrating screen sustained thousands or millions of circular loads, brittle fracture will occur even if the screen box’s nominal stress is far less than the strength limit of materials.
E—the connecting area of the baffle of material added to screen box.
The vibration fatigue S-N curve of the vibration screen material are identified through the sample test, the test material has the same characteristic, constraint condition and load as vibration screen.

It is well known that the structures of the solid materials stem from the liquid.
While how to establish the structural relationship has been a challenge in material science and condensed matter physics.
In order to optimize the performances of materials, the microstructures gradually became under control.
