The process is shown in Figure 1.
The forces, which are transformed into the forces in the mechanics coordinate system according to the formula 1, are respectively Px=42.56481069;Py=32.31504754;Pz=85.24176052.
The analysis results are as follows: (1)The finite element analysis results about the model of measured femur In the course of human walking, when the femur gets the maximum stress ,the stress diagram of the von mises was shown in Figure 9.

Abstract.
In the traditional ESO, after each iteration calculation, those material whose efficiency value meets with Eq.(1) will be removed, when no material’s efficiency meets with Eq.(1), then the RR will be increased according to Eq.(2).
We can see from Eq. (1) and Eq. (2) that the rejection ration RR can only remain unchanged or increase according to arithmetic sequence, but cannot be decreased.
Obviously, the inefficiency material is specified according to Eq. (1) and Eq. (2) in the traditional ESO, but according to Eq. (3) ~ Eq. (4) in the ESO-MVME.
Example Example 1 A plate subject to a uniformly distributed tension force A design domain of the size 2000×1500×10mm, as shown in Fig. 1, is discretized into 20 x 15 bilinear quadrilateral elements.

The maximum no-load flux density of stator teeth is 1.598T, that of stator yoke is 1.079T,the maximum load flux density of stator teeth is 1.765T, and that of stator yoke is 1.192T, it can be concluded that they meet the constraints for they are less than 1.8T.
