Simulation of penetration test of armoured plate is presented by explicit dynamics algorifhm.

Next,three aspects were considered as key technology and research challenges of bascule bridge deck surfacing here,(i)development on light paving material and research on thin deck surfacing system,(ii)numerical simulation of the mechanical properties of bascule bridge deck surfacing based on long cantilever structure and contact behaviors between interfaces,(iii)bonding layer material testing.

Study, development and application of high-strength glass fiber armour composites;

Development and application of advanced composite armor technology;

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.
