Recently, the requirement of improved structural efficiency at relatively low cost has invigorated research over cellular materials in which metallic foam material is easily fabricated.
However an optimal design of foam materials needs be based on reliable engineering researches.
Conclusion The experiments and simulations on fatigue crack growth in foam materials yielded the following conclusions

Introduction The study of laser processing of materials is becoming increasingly closely linked with all fields of science and technology, without exception.
An important factor in the formation of new material properties is both the processing conditions and the basic state of the processed materials [1].
The nanopowders obtained by laser dispersion are widely used for the preparation of highly transparent ceramic materials, including magnetically active ceramics, materials used as active elements of solid-state lasers [8].
The obtained powder materials can be used in various fields of science and technology, in particular, in the additive technology industry.

Soundless Crack is widely used in stone exploitation, partly crack of brittleness materials such as rock and concrete, and backout of building in city.
In these engineering, we must drill many holes for loading Soundless Cracking Agents, but the drilling cost is expensive including human cost and materials cost, at the same time need much time to drill these holes.
If we can know the mechanics parameters of the materials, we can numerical calculation the failure process before drilling, rectify the planning distance between holes to gain the best cracking results.

Therefore, only the viscoelastic materials lying between these two materials can store energy and dissipate energy as well.
Adding several kinds of functional materials with electrothermal function to concrete materials, the intelligentized concrete with the electrothermal function can be made, which can be used to get warm, deicing, snow melting, etc..
Conclusion With the rapid development of information science, life science and system science, the problems of the intellectualization of engineering materials have drawn peolple’s extensive attention.

In this study only the phases of materials and production were considered in the system’s boundary (cradle-to-gate) that is the most used in LCA studies of concrete [4].
In this phase of the material characterization, one can state that the concrete with fly ash incorporated may be classified as an eco-material (eco-concrete) considering that the environmental issues that are minimized are waste reduction, reduce of landfill problems and resource saving by the utilization of recycled materials.
These benefits are reflected in two of the life cycle steps, namely the extraction of materials (resources) and in the eco-concrete manufacturing.
