of heating, phase transformation, cooling, and coagulation, whose thermal process is complex. Because its heating and cooling are very quick, large internal stress will occur, which causes the components... condition, and the center of coagulated cladding approaching the substrate is the area where the tensile stress is the largest. Because the temperature gradient in this region is the largest, the thermal......
and moisture content are two important factors which affect thermal and moisture stress (TMS) of the bamboo structure wall. The TMS is not only related to temperature and moisture content, but also greatly affected by temperature gradient, moisture content gradient and rates of changing. Key words: porous media; bamboo structure; thermal expansion; moisture expansion; thermal and moisture stress 1......
characteristics related to this new technique were discussed. Key words: thin film; thermal expansion coefficient; polyimide; elastic modulus; stress 1 Introduction With the development of micro...]. However, the higher CTE of organic polymer films compared with that of the insulated substrates (e.g. ceramics or metals) will cause thermal stress build-up and even results in device failure......

J. Cent. South Univ. Technol. (2008) 15: 198-203 DOI: 10.1007/s11771-008-0038-3 Simulation of thermal and sodium expansion stress in aluminum reduction cells LI Jie(李 劼), WU Yu-yun(伍玉云), LAI... block. Thermal stress field was calculated by the other slice model of the cell at the end of the heating-up. Then stresses[A1] coupling thermal and sodium expansion were considered after 30 d start......
