The dynamic behaviors of cement-based materials, like concrete, mortar and other cementitious materials, have significant effect on safety of structures in earthquake or under impact loading, such as explosion [6].
Materials and Test Methods Materials and proportions.
The mix proportion of PVA-ECC is: cementitious materials: water: sand = 1:0.24:0.6.
This indicates that its ability to absorb impact energy higher than the previous two materials.

Composite materials or generally materials with interfaces are nowadays used in many varied engineering applications.
The considered thickness of both materials (1 and 2) was the same, i.e. t = 15 mm.
This effect can influence time to failure of structures made from materials with interfaces (e.g. composite materials).

Porous metallurgy materials is a new kind of materials developed within the last ten years, it has the properties of structural materials and functional materials.
The paper analyses the mechanical properties of oily porous materials joint from a theoretical point.
As the assumptions, the joint interface of porous and non-porous materials becomes simplified.
The porous is iron-base powder metallurgy materials; Trademark is 4001, which is produced in Quebec, Canada.
Mathematical Model for Elastic Contact of the Function Friction Materials.
