Thermal expansion coefficient refers to the extent to which the size and volume of materials change with temperature. It is an important parameter for material application and structural design, and is related to thermal shock resistance, stress distribution, and size changes after heating. ...
The term "thermal expansion" most often refers to the external parameters, which are more easily and accurately measured. Here we use "thermal expansion" to mean both external and internal parameters. Internal thermal expansion impacts a wide range of applications, but has been given less ...
Here we demonstrate a new effect in which the orientation of nematic liquid crystal molecules is altered by thermal expansion. Thermal expansion (or contraction) causes the nematic liquid crystal to flow; the flow imposes a realigning torque on the nematic liquid crystal molecules and the optic ...
Figure 2d delivers a 3D-representation of the contribution to thermal expansion along each axis (also see Supplementary Table 3). The blue region refers to the NTE behaviour domain with negative linear thermal expansion ranging from −4.22 MK−1 and −60.81 MK−1. While this coefficient ...
The thermal expansion or shrinkage of composites is often investigated by thermomechanical analysis (TMA). This article discusses how fiber orientation and nanofillers influence the expansion behavior of the composites.
The second example is a 3D metamaterial based on an octet truss, with additional members to expand the design space. A multi-objective optimization problem is solved to find the optimal trade-off between Young’s modulus and thermal expansion coefficient in a prescribed direction. The results of...
Integrators should test systems with some expansion cards installed in order to simulate a system that has been upgraded. A thermal management solution that works well in a system that is heavily loaded does not need to be re-tested for lightly loaded configurations. Thermal management ...
to 200° C. 图片(6)权利要求(14) 1. A pneumatic tire comprising at least one component, the at least one component comprising a rubber composition, the rubber composition comprising a diene based elastomer and an inorganic negative thermal expansion (NTE) filler comprising at least one compound...
Moreover, µn f represents the dynamic viscosity of the nanofluid, ρn f refers to the density of the nanofluid, (ρβ)n f denotes the thermal expansion coefficient of the nanofluid as described in the Brinkman's model, ρCp n f denotes the heat capacitance of the nanofluid, αn f ...
2.4). In this condition, the thermo-physical properties of the substance (thermal conductivity, thermal expansion, and elasticity) can change depending upon the temperature [107,108]. In the case of steel, it has been found that thermal conductivity decreases, thermal expansion increases, and ...
