The raw and auxiliary materials are mainly from domestic suppliers, and the usage ratio is shown in Table 2.
The use of phase-change materials in the production of phase-change gypsum plasterboard is the main stage causing eutrophication, which can be improved from the use of phase-change materials to enhance material utilization efficiency and to reduce waste
(4) The transportation process of various raw materials and energy also has a certain environmental impact on the life cycle of the two kinds of gypsum boards; therefore, transportation distance of various raw materials and energy can be optimized or reduced, and symbiotic park of raw materials can be built to reduce the load on the environment.

Relationship between bending solutions of FGM and homogenous circular cylindrical shells Zeqing Wana, Shirong Lib School of Civil Science and Engineering, Yangzhou University, Yangzhou, 225127,China ae-mail:zqwan@yzu.edu.cn, be-mail:srli@yzu.edu.cn Keywords: functionally graded materials, circular cylindrical shell, bending solution, analogous transformation Abstract: Based on the Love’s shell theory, relationship between bending solutions of functionally graded materials (FGM) and homogenous circular cylindrical shells was studied.
Due to gradual variation in the microstructure of these materials, which causes the continuous and smooth variation of properties, the problem of mismatch between the properties of bonded materials at the interface that could cause to debonding in high temperature, would vanish.
The volume fractions of all the constituent materials should add up to one, i.e
