Scattering of SH Wave on Periodic Cracks in An Infinite Plane of Piezoelectric/Piezomagnic Composite Materials Wei Shi1, a, Lixia Ma1 1School of Mathematics and Computer Science, Ningxia University,750021, Yinchuan, China ashw@nxu.edu.cn Keywords: Piezoelectric/piezomagnic materials, SH wave, Periodic cracks, Singular integral equation.
Introduction Due to the inherent coupling nature, piezoelectric materials and piezoelectric/piezomagnic materials have attracted wide application in engineering.
Piezoelectric materials and piezo- electric/piezomagnic materials in mechanical behavior are brittle and susceptible to crack- ing, Therefore, it is important to study the electro-magneto-mechanical interaction and fraction behavior of those materials.Great efforts have been made to study the fracture behavior of the materials.

High material hardness and low fracture toughness decrease economy and application of end milling in brittle materials such as ceramics.
However, with the increased use of brittle porous materials in composite tooling applications end milling in combination with more machinable materials are increasingly being used to achieve higher material removal rates.
For many porous materials a spherical shape is acceptable.

Introduction Woven bags are widely used for the packaging products such as rice, flour, cement, fertilizer, chemical materials, metal products and so on.
The production of these materials is very great.
There are some advantages by using robot load-unload materials, such as gripping reliably, moving flexibly, placing neatly and so on.

Introduction Material Science plays a very important role in human history.
Therefore, the requirement of integration and sharing of computational resources and management of the material data is necessary for the researchers in material science.
The e-science platform is capable of providing the need for material scientists[1].
The safety evaluation for the pipe network of natural gas is a very typical application in material science.
