The Reissner’s plate bending theory with consideration of transverse shear deformation effects is adopted to study the fundamental fracture problem in functionally graded materials(FGMs) plates for a crack parallel to material gradient.
By means of the asymptotic expansion method, the crack-tip higher order asymptotic fields which are similar to the famous Williams’ solutions to homogeneous materials are obtained.
(3) Crack-Tip Higher Order Asymptotic Field The studies of Delale et al. [6, 7] show that the crack tip stress field would be equipped with the same square root singularity as that of homogeneous materials when the material properties of different composite materials at the interfaces are continuous.

Piezoelectric elements are mainly made of polymer or ceramic materials.
Piezoelectric strains Piezoelectric elements are mainly made of polymer or ceramic materials.
The values of their material constrains are directly connected with materials used- see Table 1.
Comparison of the piezoelectric materials may be made roughly using the Table 1.

Method The PPGS method for laser material processing on freeform surface is based on two principles discussed as follows.
Six steps are involved in performing the procedure of laser material processing on freeform surface.
Application The key technique for laser materials processing on freeform surface part is the implementation of the laser spot marching along the freeform curve paths on the surface, at desired speed and energy density that can initiate the expected laser-matter interaction.

We select high barium ferrite as the active material of the battery cathode materials, and on the basis of the traditional high-speed rail barium preparation were added silicon sodium (Na 2 SiO 3 · 9H 2 O) and potassium permanganate (KMnO 4), as a synthetic additive to improve the stability of the battery and discharging performance.
The laboratory obtained high-purity potassium ferrate as starting materials, in the solution obtained with the barium salt (barium hydroxide or barium nitrate) Reaction Barium Ferrate precipitation, high iron of a high purity barium product obtained was purified by separation.
