Therefore, it is need to find the process which can produce fine grained and highly oriented structure without loss of mechanical properties.
Therefore, it is proposed that excess Te and CuBr added Bi2(Te0.94Se0.06)3 compound produced by hot extrusion may improve the thermoelectric performance without loss of mechanical properties.
The annealing process could affect the thermoelectric properties through the change of the behavior of impurities [12], structure [13] and disorder effects [14,17].
Therefore the change of (1 1 0) plane which is perpendicular to the basal plane appear to affect the thermoelectric properties.
The fine grain structures are expected to improve the mechanical properties according to the Hall-patch equation.

Mathematical models that describe changes in the elastic-strength properties of epoxy polymers during climatic aging, depending on the accumulated quantitative values ​​of the acting environmental factors, have been developed.
A possible way to solve the above problem can be the development of mathematical models for changing the properties of materials depending on the quantitative values ​​of environmental factors.

Simulation Analysis of Factors Affecting Thermal Stress of Thin Films.
In addition, the thermal stress of the film is affected by many other complex factors.
In addition to the above-mentioned main factors, other factors such as film thickness, size, and curvature also affect film stress.

The relevant mechanical properties of materials is analyzed to predict the macroscopic stress distribution, residual stress and other parameters, which realized the simulation of micro-macro properties and the analysis of toughening mechanism of the material.
However, because the form mechanism of residual thermal stress is quite complicated and it is affected by a lot of factors, there is not enough comprehensive understanding on the residual thermal stress so far.
Generally speaking, the residual thermal stress in material is influenced by distribution of the second phase, the particle size, the volume content, particle size ratio, and many other factors.
Al2O3/TiB2 is chosen as material and its properties is shown Table 1.
The volume content of the second phase can greatly affect the residual thermal stress, the simulation result shows that there exist an optimal value of second phase which is much beneficial for reinforcement of the mechanical properties.

One way to overcome this is to replace it with materials that are environmentally friendly and safe for health, namely biodegradable plastics with high mechanical properties, where the mechanical properties are affected by the drying temperature.
The combination of temperature and drying time factors will produce optimal conditions for all analyzed parameters [15].
The plasticizer nature and content greatly influence the properties of the materials [20].
The mechanical strength of biodegradable plastics including tensile strength and elongation can also be affected by the presence of cracks.
