Introduction With the rapid development of modern industry, piezoelectric materials are more and more widely used in smart materials and structures such as electro-mechanical sensors, transducers, ultrasonic generators and actuators.
The electro-mechanical coupling response of these materials has helped to establish plentiful styles of devices.
Piezoelectric bi-materials with an interfacial crack near a circular cavity Fig. 2.
Fig. 2 shows the piezoelectric bi-materials' conjunction.

Gross: Effect of different supplementary cementitious materials on mechanical properties of high performance concrete.

On the site grouting test and compare the compressive strength of the stones of the body and the size of the diffusion radius, and compare the grouting materials with pure cement materials.
Through the comparative and analysis, the reasonable grouting materials are choosen.
Comparison analysis shows: The core compressive strength of pure cement materials and montmorillonite with cement mixing materials has little difference.

The process of second scratch includes removing materials partial rupturing from workpiece, materials of workpiece surface and pushing and pressing chips.
It indicates fewer materials are broken during second scratch, while peak value improves for increasing of depth of cut and cutting area
