In the numerical simulation, a coupled solver is used; fluid material is supposed to be ideal gas; momentum is in the form of second-order upwind dispersed mode; pressure and velocity coupling uses the SIMPLE algorithm and airfoil surface is the no-slip thermal isolation boundary.
The structure material parameters are showed in Table 2.

Article first quantitative analysis of milling material removal during the effect of work piece model, using matrix perturbation theory gives the work piece modal approximation, fast algorithms.
Artifact removal of material in the manufacturing process, stiffness and mass matrices also changed.
Taking into account the rough material removed, you will need to take into account higher-order perturbation.

These stresses can decrease the properties of materials and cause flaw.
Therefore, it is important to find the residual stresses distribution in green compact for ensuring the high performance of materials.
