The three-dimensional structure of scaffold is a key factor to treat spinal cord injury in tissue engineering method.
The used materials in the study can be divided into two categories in spinal cord tissue engineering.
Natural Materials.
Synthetic Materials.
With the development of tissue engineering, synthetic polymer materials are widely used.

To better understand this closed loop, it’s important and significant to model the whole loop from a system engineering point of view.
These vehicles are classified as end of life vehicles (ELVs) and are potential sources of recoverable, reusable, and recyclable materials [1].
By taking materials flow, information flow, energy flow as well as the interactions among processes into account, it’s possible to do a holistic modeling for the whole ELVs infrastructure so as to have a better understanding and to find the opportunities to improve the infrastructure from system engineering point of view.
This work expands the input and output of IDEF0 to include materials, information and energy flow (see Fig.2) in order to solve the problems of ambiguous materials, information, and energy flow in the ELVs recovery infrastructure.
From system engineering perspective, the ELVs infrastructure was divided into four sectors in this work: vehicle design, vehicle manufacturing, vehicle use and vehicle recovery (see Fig.5).

Recently, the sheets have been applied in automotive engineering in order to reduce the weight of commercial cars.
However, the properties increase springback amount when these materials are subjected to any forming process.
The most famous yield function is Von-Mises function that suggests isotropic yielding behavior for all metallic materials.
Advanced materials such as aluminum alloys show a strong effect of material orientation on their yielding behavior, that is so-called as anisotropy.

Most engineering simulations of fishing gears were based on the physical model of knotted netting [4-6].
Thus, the environment of the ocean was imitated vividly in this engineering simulation in computer.
The actual inertial mass coefficient of tuna purse seine under sea water might be affected by many factors (such as the density of netting materials, modulus of netting elasticity, sinkers and water currents).
Conclusions The engineering simulations demonstrated that the inertial mass coefficient was a key factor to influence the sinking and stability of knotless netting model used in tuna purse seine.
