Due to the extensive sources and simple processing of the material, the equivalent target will reduce the test cost greatly.
The geometry (such as the shape and thickness), the choice of material and the installation should be designed correctly and reasonably [11].
We choose LY-12 aluminum as the material, of the circular structure, diameter and thickness, and the method of rigid fixation.

This study tries to explore the deformation and fracture property of plate of brittle materials under uniform pressure, which can be references for the design of mold in elastic deformation machining method.
Fracture probability of brittle materials always obeys the Weibull distribution.
For glass plate with different depth and materials, it is not convenient to study their fracture property using specimen experiment every time.

We remarked that ionized impurity scattering mechanism plays a dominant role in this material at low electric field.
Introduction Electron transport in HgCdTe (MCT) has been getting much attention for many years mainly because of the aptitude of varying its transport parameters with composition and the growing technological applications interest in this material [1].
The advantage of this technique is its ability of reproducing a complete picture of carrier dynamics based only on microscopic material parameters such as effective mass and scattering parameters [5].
(2) In the case of a bulk homogeneous material the unknowns do not depend on space and then spatial derivations can be neglected.

In order to satisfying three directions stiffness requires of engine mount, the optimization math model has been established, mount material and geometry parameters have finally been calculated by selecting appropriate arithmetic.
This method has a lot of disadvantages: on the one hand, this process will waste a lot of time and materials; On the other hand, simply changing the size of the mount can not simultaneously meet its every direction rigidity requirement [1].
Taking E=5.04Mpa as the whole compression process of material elastic modulus.
