S matrix on the sub-matrix Si for common form is [5]: (1) .They are all elastic matrix coefficients and only associated with the material type.
The matrix form is Jacobi Matrix： (2) In determining the displacement shape functions, the geometry of the unit, Jacobi Matrix and the material, we can also uniquely confirm the stress matrix S.

Introduction It is important for the concrete industry to need moisture sensors in the sand bins or in the concrete bins because mix design assumes that aggregates, cement and water are present in the correct proportions, according to the dry material weights.
However, the moisture in the sand varies largely and the sand that get from river bed usually mix other material such as mud.

However, considering the roughly making, discreteness of model materials, and some detailed structure, such as joints and bolts, can not be accurately modeled, the most important issues, including the bearing capacity, instability and failure characteristics, can not be accurately simulated.

Introduction Because of the synthetic excellent mechanical properties of high hardness, low friction coefficient, high temperature resistance, (Ti, Al) N film is one of the most widely used film materials on the process research and application.[1-6] Many experts and scholars at home and abroad for its single process parameters (such as: arc current, substrate negative bias, transition layer type and thickness, nitrogen and argon gas partial pressure of the magnetic field strength, target based distance, temperature, etc.) has done a lot of testing and analysis on the impact of the hardness of titanium nitride film and film and substrate binding force.[7-10] But, the links between the various process parameters and the relationship between primary and secondary effects of titanium nitride films have rarely been reported.

To sustain such amounts of temperatures, the design of the disc and materials incorporated should support the high thermal as well as mechanical stresses.
The thermal and stress analysis of disc brakes by checking for the optimal material from suitable materials like Stainless-steel, Cast Iron, and Carbon-carbon composites was done.
Also, two Aluminum Metal Matrix Composite materials were studied.
Another objective of this project was testing different materials for the disc brake and find out which material is better in terms of strength, deformation, stress distribution and heat dissipation capacity.

The earliest application of AE in concrete material was performed by Robinson [6] in 1965.
The application of AE technique for homogeneous material has matured considerably.
However, AE appearance due to the fracture within heterogeneous material was obscure.
When RC was fractured, AE events of many frequencies would perform for the cracks over different materials such as aggregate or cement mortar.
