If a high-conductivity driver expands a low-conductivity specimen or the specimen is given an inner coating, for example of copper, specimens of bad conductors and nonconducting materials, such as engineering ceramic, which is appealing due to its unique features especially the high strength, high hardness and low density may also be tested.
This research can be available for reference for the application and development of fragile material test technique.

When an amplitude of temperature reduction is high, the tensile stress of elasticity materials may be larger, so repair materials should have ductility and elastoplasticity materials are considerable.
Materials' adhesive strength is1.5 MPa.With the width of the crack increased, the plastic of the repair materials we need decreased, so we mainly focus on the elastoplastic performance of repair materials when cracks' widths are small.
Using the perfusion method to repair, the elongation of the materials should reach 171.5% when the elasticity modulus of material is 100MPa.the elongation of the materials should reach 165.4% when the elasticity modulus of material is 300MPa.
