Glasses and diamond-structure solids present an interesting problem as they display negative expansion coefficients at moderately low temperatures. At least one of the diamond-structure solids shows a return to positive behavior in the low temperature limit and others seem likely to do the same thing...

The Thermal Expansion of Solids 来自 掌桥科研 喜欢 0 阅读量: 50 作者: GC Fletcher 摘要: The assumptions involved in two well-known formulae due to Grneisen are investigated and with these assumptions an explicit formula for the volume of a solid as a function of temperature is derived. ...

The expansion of the soil was more pronounced in the vicinity of the two piles. The maximum soil expansion outside the FRPC and FR piles was 4.702 mm and 4.815 mm, respectively, which were close. However, soil expansion in the center of the two piles reached 5.677 mm due to the ...
Current reported cellular metastructures can either achieve only tailorable thermal expansion or obtain only tunable Poisson's ratio. By contrast, here, we develop a kind of lightweight cellular metastructure which incorporates coupled tailorable thermal expansion and tunable Poisson's ratio. That is a ...
