There exist multi-field coupling effect in prefabricated defects polymer materials under loading.
It is important to understand the rheological properties of such pyromagnetic effect in the loading material with visco-elastic plastic damage, which would be valuable for rational use of materials, design of new materials, production safety, and accident prevention, etc. [1, 2 , 3, 4, 5, 6, 7].

Preparation System Design of Filling Material with Coal Gangue as Coarse Aggregate Youxia Sun1, a, Dawei Ren2,b 1Key Laboratory of Mining Disaster Prevention and Control of Education Ministry, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China 2College of Natural Resources and Environmental Engineering, Shandong University of Science and Technology, Qingdao, Shandong, 266510, China asyxljl@sohu.com, bdawei_ren_2000@163.com Keywords: coal gangue, green mining, preparation system, filling material Abstract.
Thus far there are mainly four kinds of filling materials, which are high water materials, solid materials, paste filling materials and paste-like filling materials.
However, the preparation systems of the three filling materials are located on the ground, which must cause the secondary pollution by coal gangue processing and increase the transport cost by lifting the coal gangue out of the shaft and carrying the filling materials to underground.
The performances of the two materials developed meet the requirements of gob-side entry retaining and backfilling.

With regard to the patents, it could be observed that some palygorskite-based materials have already been patented.
The results show that palygorskite is an excellent alternative for obtaining materials with photocatalystic activity.
The articles found approach the synthesis of these materials by different ways and with excellent results on the degradation of pollutants.

Micromechanics aim at determining macroscopic material properties of functionally graded materials from microstructures and the macroscopic material properties of materials that consist of them.
Due to functionally graded materials behaving mechanically different to both homogeneous and laminated materials, Applying traditional micromechanics to predicting material properties of functionally graded materials have no strict theoretical foundation, which is most likely to lead to large errors.
