Entering the information age, information, intelligence and the concept of sustainable development constantly enrich and affect the meaning of architecture.
Overlap between complexity and simplicity is retained overall simple premise, allowing the building to become irregular and complicated, a strong contrast effect to form a complex and simple, or produce a kind of extreme syllable rhythm, even to make the structure and component reduced to decorative factors in pure.
Structural expressionism,to the structure as a means of expression, is not very concerned about the fine performance of the mechanical role of the member and the building structure, not the pursuit of industrialization and economic benefits of the construction, but rather focuses excavations sculptural art factors of the structures.
In short, sculpture tendency is steel structure architects use their imagination and creativity, taking inspiration from the natural properties of materials and structures, combine with new aesthetic intention, and create a out of the ordinary image in the construction practice, this is also the pursuit of structural performance.
In the face of the world cultural convergence and traditional culture is disappearing cultural crisis, technology development must also consider the human factor, emotional, psychological field, identity and break through the exploration of Architectural Technology in human psychological field.

The particle size of the coarse grogs has a minor effect on the physical properties of crucible bodies.
The physical properties obtained are better than those of the imported crucibles, as examined in our previous work [2].

Due to their properties, fibers have been widely used in the textile industry for thousands of years.
Overall, SF has a wide range of potential applications in the biomedical field due to its unique combination of physical and biochemical properties.
The degradation of silk fibroin depends on multiple factors such as the amount of material and its architecture, the characteristics of the microstructure, the natural degree of crosslinking and the site of implantation [2].
It was found that the pill after being immersed for 2h in the PBS turned into a material with very low strength and poor structural properties.
Moreover, SF can be a potential candidate not only as a coating material, but also as a base material for medical devices due to its mechanical properties.

Mercury, salt water, ionized gases all have this property to various degrees [1].
Bradley C et al. (2018) [5] investigated how a magnetic field affected the electrolyte's passage through the working gap and how it affected the machining results.
By closely examining the crucial elements that have an impact on the process and reducing variance through controlled testing, the goal is to decrease the likelihood of errors by Taguchi's use of orthogonal arrays because it is makes it possible to evaluate several factors at once in an effective manner.
Furthermore, the type of material also affected on machining rate as show in figure 7.
Figure 13 to 16 explained the effect of each factors with and without magnetic field.

To investigate the mechanical behavior and stress distribution of the joint, a full size model test of the typical SCT joint is conducted.
Following assumptions are adopted in the finite element analysis of the test joint model. ① The thickness of weld root and the residual stress of welding are ignored in the load-bearing calculation of the test joint. ② The steel is isotropic material, and obeys the Von-Mises yielding criterion. ③ The idealized elasto-plastic model is adopted as the constitutive relation for steel, and the mechanical property of steel is obtained through the material test [6].
When the load factor goes up to 1.05, the inflection points appear on each force-stress curve gradually.
As shown in Fig 6, the slope of the curves decreases obviously at the turning point of the load factor of 1.05.
The interpolation affects the precision of calculation results as well.

It was observed that the lamellar microstructure significantly affects the superplastic forming process and the uniformity of the thickness profile after forming.
Nevertheless, the superplastic properties progressively improved by special processing methods, like as special thermomechanical treatments [5,12–16], severe plastic deformation [17–19], hydrogen technologies [20–22].
The most of theoretical and experimental studies of superplastic properties and deformation behaviour in the superplastic conditions were carried out on Ti-6Al-4V alloy.

However, the mechanical strength of HA is relatively low.
However, the relatively low bond strength between the HA coating and the metal substrate and the resulting potential weakness in the prosthesis system has been the main limiting factor of the plasma-spraying technique [5].
The bond strength is mainly affected by the differences of physical and chemical properties of the HA coating and the metal substrate, which cause residual stresses in the coating.
It firmly bonded to the substrate without gaps and obvious interface between the coating and the substrate, greatly improving the mechanical strength of the coating.
