Introduction Wood has a number of excellent properties as a building material: it has a high strength to weight ratio, it is a good thermal insulator, it can be shaped and connected to form larger structures and it is one of the most sustainable and environmentally friendly materials.
Furthermore, the natural durability of freshly cut timber was rather extensively studied, but up to our best knowledge there are not many reports regarding the performance of wooden materials after certain period of use.

The SWT parameter after the modification was used as well as under multiaxial proportional and nonproportional loading for materials crack according to Mode I.
Chen et al. criterion (1999), [20] Chen and others proposed two criteria: one for materials characterised by Mode I crack and the other one for materials characterised by Mode II crack.
For materials characterised by Mode I crack the critical plane is a plane of maximum normal strain range ∆εn.
For materials and loading characteristic for mixed Mode crack the octahedral or the different plane was accepted.

In the presented calculations the impact of the heated punch to the material is not taken into account.
In the deformation of the material the areas of plastic flow and stress concentrators occur.

Ningbo has been identified as a number of circular economy demonstration sites, such as science and technology Park, textile Park, chemical industry park ect.
The sites strengthen the industrial chain matching, urge symbiotic relationship among the enterprises, realize the transfer between material and energy gradually, and recycle of resources use and pollutant emission reduction
The great changes attribute to promotion of technological innovation, the stress on material recycling, and the transformation of extensive management in mining and manufacturing and the traditional industries.

Study on Solid Phase Crystallization of Silicon films Deposited on Different Substrates Qingdong Chen1, a, Junping Wang 2,b and Yuxiang Zhang3,c 1Department of Physics and Electronics Science, Binzhou University,Binzhou 256600, China 2 Key Laboratory of Material Physics of Ministry of Education, Physical Science & Technology College Zhengzhou University, Zhengzhou, 450052 achenqingdong99@ yahoo.com.cn, bwangjunping88@ yahoo.com.cn, czhyx@zzu.edu.cn Keywords: amorphous silicon;anneal;PECVD;porous silicon.
For different substrate material, their thermal expansion coefficient , structure status(such as: average bond length, average bond angle and otherwise parameters) are different from silicon, the more close to silicon, the crystallization of thin film the more relatively easy; otherwise, the crystallization the more difficult.
