The discrete element method was developed based on the principle of molecular dynamics by the American scholar Cundall P.A. in 1971, which is used to study the discrete particle materials.
In granular materials, force is transmitted from one particle to the next via their contacts.

Introduction In modern science and technology industry piezoelectric transducer has a very broad impact.
Design Of System As one method to measure the piezoelectric constant, the key to static test method is depend on surface of the piezoelectric material under uniform compression to ensure accurate measurement of static method.
The A/D calibration circuit Test Results And Analysis To test the system of piezoelectric constant test,YT-4 of the piezoelectric material, its size of φ 20 × 2,the nominal value of piezoelectric constant is 242×10-3Vm/N.
The set value of pressure and the rest of pressure is measured by digital pressure transmitter with the accuracy class is 0.5%FS, accurate value of the instantaneous pressure on piezoelectric material is obtained.

For brittle materials such as rock and concrete, generally occurred localized damage and fracture under the impact loading, and the localized damage and fracture will seriously reduce the material strength[6].
For simplicity, this analysis assumes that all the blocks are homogeneous spheriform materials, the total kinetic energy of each projectile block before impact can be calculated as: (1) where m is the mass, vi is the translational velocity, I is the moment of inertia, and is the rotational velocity of the projectile block.

Materials no penetrating and not-be-to-pull, that is unilateral boundary conditions, are the restrain conditions of the comparative situations among objects.
The boundary conditions: 1) Constraint conditions: oil tree section constraints 2) Load: The pressure of internal mud: 105MPa; the weight of drill string: 300t 3) Materials: Ideal elastic plastic material C.
The solutions are using high strength materials or improving the structure to improve the reliability of test tree. 3) In each threaded connection area, stress is non-uniform.
