Introduction The yield characteristics for materials vary significantly due to their complicated microscopic structures, even though for the isotropic homogeneous materials [1-3].
The value of and are concerned with the stress states in materials.
For materials under the stress states, the there principal stresses are (15) .
It shows that this new criterion can reflect the yield characteristics better for different materials.
When materials are in the state of yield, themay be approximately 0.5 [6, 7, 15].

In these composite materials, the transfer of elastic deformation between the filler and the matrix materials seems to be less effective, leading to interface fractures [35].

Chitosan become one of the most beloved materials as a natural scaffold material because of its ability to mimic the extracellular matrix.
What is more, raw materials are simple and easy to get.
Chitosan can form an increasingly high degree of artificial extracellular matrix with other composite materials.

The shape memory alloys are materials that can change their shape by applying thermomechanical treatments.
In order to design SMA materials, the stress-strain-temperature relationship is necessary.

The principle of multiple sparks EDM (a)ordinary EDM (b)multiple sparks EDM Fig. 2.The principle of saving power (2) In ordinary EDM, for high resistance materials such as conductive ceramic and single crystal silicon, its internal voltage drop is great, which makes the discharge current decrease, and makes material removal rate decline.
In theory, for each pulse, because of producing a discharge at the tool electrode positive, and also produces another discharge at the same time in the tool electrode negative, material removal capacity of every pulse of multiple sparks EDM should be consistent with both materials’ removal rates of the single positive tool electrode and single negative tool electrode of ordinary EDM.
