Because of the lack of knowledge of industrial design greatly affects the efficiency of industrial design corporate design activities.
Industrial design must also consider the social and natural factors , so that the healthy and sustainable development of human society , maintaining harmony between man and nature .
Performance of industrial design From the above analysis of the connotation of industrial design and industrial design features can be seen with the basic properties of creative design , binding , multiple solutions , iterative feedback and so on .
Another designer also take into account various factors existing level of technology and production conditions as well as legal , environmental , ethical , and cultural .
First, because the object is also designed constituted by a variety of factors , any one of the factors that affect the design changes will lead to solving design changes.

In this context, the aim of this work was to evaluate the microstructure and tribo-mechanical properties of Ti6Al4V alloy manufactured by SLM and the effects of subsequent stress relief heat treatments on such properties.

Introduction The foremost representative of cement composites is concrete which gains its properties through cement hydration.
During these reactions, hydration heat is produced which is manifested by an increase in temperature inside the concrete element during curing when the concrete obtains its mechanical properties.
Fire resistance of concrete involves a great number of factors.
The ambient temperature is set to be constant (20 °C) and the specimens are placed in an air-conditioned chamber so as to avoid affecting the reactions.

Some other factors such as fiber surface area, structures and porosity are relatively neglected in concern of adhesion between fiber surface and the matrix [9].
This phenomenon is closely related to the decreasing hydrophobic properties of fibers and promotes reactions of polymerization of the two materials components.

In this work acetylated corn starch was taken as the raw material and its filming property was studied through single-factor and orthogonal array design experiments.
During the past few years, biodegradable polymers with suitable mechanical and physical properties have received particular attention and can be potentially used to replace petroleum-based plastics [5-6].
Testing film properties.
The comprehensive properties of the films were evaluated with full marks of 100 points.
In the optimized film-forming formula A1B3C1D1, the most important factor that affects the film properties should be glycerol concentration, sequentially followed by acetylated corn starch concentration, PVA concentration and the glutaraldehyde concentration.

Progressive Failure Approaches take into account the degradation of stiffness properties, due to the onset and evolution of the intra-laminar damage at element and lamina level, in the frame of a Geometrical and/or material non-linear Finite Element Model, to determine the load carrying capability of composite structures [7].
The proposed material constitutive model has been implemented in the FE software ANSYS© as a User defined material subroutine (USERMAT) and used to simulate the mechanical behavior of an Open Hole Tension specimen.
Instantaneous and Gradual degradation Models – A novel Gradual degradation model According to the Instantaneous degradation Models (IDM) the material properties associated to each failure mode are instantaneously reduced to a small fraction, according to the degradation factor K, of their original value, so that the damaged ply (at element level and for each integration point) gives a negligible contribution to the load carrying capabilities of the structure (ply-discount technique).
Among the lamina properties taken from [10], the values of the Intralaminar fracture thoughness have been listed in Table 1.
The proposed energy-based Gradual Degradation Model was found to overcome the mesh dependency problems affecting the standard instantaneous and gradual degradation models, providing, at the same, a very accurate prediction of the mechanical behavior.

Samples for mechanical properties test were shown in fig.3 and fig.4.
It can be seen that as the content of mineralized collagen increasing, the mechanical properties of the composite cements overall showed a decrease trend.
Bone cements frequently used in the clinic is polymethyl methacrylate (PMMA),which can not be degraded in vivo, affecting the bone healing.It is a hotspots to develop a biodegradable bone cement to replace PMMA.
produced and in vivo mechanical properties of the composite cement will be investigated in the future.

Dielectric Properties Enhancement in Polybenzoxazine Composite at Multi-Frequency Range N.
In this work, the dielectric properties of a surface-treated BST powder-polybenzoxazine composite were studied.
However, it was reported that the uniform distribution of ceramic filler is one of the important factors that strongly affect the dielectric properties in 0-3 polymer-ceramic composites [3].
Thus the surface modification of ceramic fillers was interested as the method to improve the dielectric properties in PBZ-BST composites in this research.
Dielectric Properties From Figure 2, it can be seen that at the same frequency, dielectric constants of the composites increased with the volume fraction of the BST ceramic powders.

Then, the aim of this study was to evaluate the impact of using different contents of bamboo particles in the particleboard core, on their physical and mechanical properties.
The apparent density of the panels was determined using the average density of each of the specimens used in determining the physical and mechanical properties.
