After hundred years of development, the types of piezoelectric materials develop from the original piezoelectric crystal to the piezoelectric ceramics, the piezoelectric polymer, the piezoelectric composite material and piezoelectric alloys and other materials.
But piezoelectric ceramic materials belongs to brittle material, it will be broken when the piezoelectric materials are closed to the pavement, so we should consider the mechanical characteristics of piezoelectric materials; moreover, pavement will stand axle load for millions of times and even hundreds of millions of times in design working life, too much stress can cause fatigue damage of piezoelectric materials, therefore, not only the theoretical data, but also the material characterization and the coupling of the material characterization and the pavement should be taken in consideration to judge the position of the piezoelectric materials.

Research and Design of a Steel Material Sorting Instrument based on Eddy Current Qi Lan 1, a, Fuhua Ma 1, b, Zheng Nong 2, c 1Institute of Friction Materials, Guangxi University for Nationalities, Nanning, 530006, China 2College of Education Science, Guangxi University for Nationalities, Nanning, 530006, China aemail: lanqigxmd@163.com, bemail: gxmfh@163.com ,cemail:nongneal@163.com Keywords: Mixing Material in Steel; Eddy Current Probe; Eddy Current Testing Abstract.
Based on the principle, a Steel material sorting instrument was made to detect the steel permeability level, through the permeability level, combined with the central processing circuit steel hardness values reflect iron parts, materials and the carbon content of steel, mixing nondestructive sorting.
In the production process, the iron and steel materials and components of the mixture have occurred from time to time.
If only the metal material is different, the other parameters are fixed, changes of the coil impedance will be only related to metal materials.
