Introduction Cellular materials can dissipate a large amount of kinetic energy at nearly constant stress during large deformation.
They can serve as effective and efficient energy absorbers to mitigate impact/blast loading if the base materials are properly selected and morphology of microstructures is well designed.
It can be seen that SKYDEX® has a similar performance with egg-box and woven textile materials, and outperforms aluminum foams.

For the developed surface area of Xishuangbanna Dai's houses' roof be equal to about 85% of the total floor area, the reasonable choice for materials of roof frame has the important meaning for conserving energy and materials.
Therefore, replacing wood with the fast-growing and renewable material to construct the roof frame of Dai's house has great significance on the conservation of energy and materials.
Although this method has solved the problem about the local compression of bamboo walls, because of the large amount of slurry filling, the bamboo poles' self-weight has increased; more over it makes the construction efficiency lower and waste materials.

Introduction For lower emission and higher crashworthiness in automobile industry, high strength steel sheets and aluminum alloy sheets are increasingly used as light-weight materials.
However, these materials exhibits much more significant spring-back phenomenon than ordinary mild steel sheets in forming process, which could result in severe geometrical deviation of deformed part.

One of the approaches to enhance the zirconia-based ceramics stability is the development of composite materials much less subject to adverse effects of t→m transformation.
The stability parameters for these two types of materials are also virtually the same.
Inferior microstructural uniformity, non-uniform distribution of component phases, combined with higher ‘tetragonality factor’ values lead to mechanical instability in ZTAC materials.
