When ultra-light materials with periodic micro-structures are manufactured and applied in engineering,there always exist stochastic variations in matrix materials,topology and size of microstructures,etc.

The weldability and existing problems for resistance spot welding of ULSAB material were analyzed,the composite jointing technique"spot welding+bonding"was presented for improving the fatigue strength,torsion stiffness and impact-resistance force of advanced high-strength steel AHSS components and body structure.

Heat Dissipation Analysis and Design of Ultra-light Cellular Materials and Electronic Equipment;

Through the GRC density,mechanical properties testing include tensile strength and flexural strength test,and thermal conductivity analysis,it can be found out with appropriate alkali resistant glass fiber ratio,water ratio,water-cement ratio,light material ratio,the material can achieve the best performance,such as density of 0.

Natural environmental corrosion protection technology database for light materials was designed and established making use of material corrosion data and environmental corrosion data of natural environmental test network,under the Windows operating system,and adopting SQL database management system.

As a kind of geotechnical material, light material is made of artificial materials, the primary character of which is that it is lighter than common soil while the intensity and the deformation feature may be equal to or even be better than good soil.
