For different materials and different thickness of plates, it often requires numerous experiments to find the suitable shape and structural parameters of nodes connected stamping dies; ② for the effect on the detection of connection，there is no reasonable basis for evaluation and corresponding test equipments.
Then at the upper corner of sheet flowed to the surrounding material.
Therefore, the reasonable punch diameter of a variety of different materials and different thickness of stamping connection could be analyzed by deformation.

In many cases, composite materials have superiority over metals.
Damage by an impact takes the form of delamination of materials, and the rupture of fibers and/or layers; it could be a permanent change in materials even if damage is limited to a partial area.
Impact load causes effects on an adhesive part of different materials, and create a stress wave

Effect of annealing temperature on structural and electrical properties of bismuth ferrite thin film Minfang Zhang1,a, Jingsong Liu1,b 1State Key Laboratory Cultivation Base for Nonmetal Composites and Functional Materials, Southwest University of Science and Technology, Mianyang 621010, China azhangminfang623@163.com bferam@163.com Keywords: bismuth ferrite, sol-gel, electrical property Abstract.
Introduction Multiferroic materials have attracted much attention because two or three of the properties (ferroelectricity, ferromagnetism, and ferrroelasticity) occur in the same phase [1].
Iron nitrate nonahydrate [Fe(NO3)3·9H2O] and bismuth nitrate pentahydrate [Bi(NO3)3·5H2O] were used as raw materials.
The precursor solutions of bismuth and iron nitrate were prepared by adding the raw materials to 2-Methoxyethanol and citric acid under heating and stirring.
