Piezoelectric actuators are being increasingly studied and used in different areas of science and technology due to their nanometer displacement resolution, wide bandwidth, fast response and high stiffness [2].
Consequently, the feasibility of adopting piezoelectric materials as actuators and sensors for controlling vibrations in flexible structures has received increasing attention.
Piezoelectric materials provide inexpensive, reliable, and non-intrusive means of actuating and sensing vibrations in flexible structures.

The single spinel phase powder was obtained when the precursor materials with a carbon powder of 5% in mass were used.
If using other materials to replace the iron powder as the fuel to prepare the Ni-Cu-Zn ferrite powders, it will avoid precursor materials mixed non-uniform and sintering temperature uneven because of oversize of the iron powder particle-size [5-8].

Along with the interference fit parameters, the consideration of materials is mentioned as well.
Principally, the selection of materials for an interference fit is usually a consideration of both shaft and hub, as a pair of materials.
A typical study of different mating materials in interference fitted assemblies was carried out by Udupa and Sogalad, the paper presented the experimental results of different mating pairs of materials [9].

In this articles we will develop a new in-situ residual stress detection method based on flexible hinges for thin-film materials, then described the detection principle theoretically and simulated its properties by FEA method.
Introduction The methods of thin-film materials growth or deposition include physical vapor deposition (PVD), chemical vapor deposition (CVD) and thermal oxidation [1].
