Numerical evaluation of expansion loops for pipe subjected to thermal displacements
Curved and Layered Structures, 2021 The thermal expansion can lead to the high stress on the pipe. The problem can be overcome using expansion loops in a certain length depending on the material’s elastic modulus, diameter, the amount of expansion, and the pipe’s allowable stresses ...

On the switching between negative and positive thermal expansion in framework materials
Materials Research Letters, 2019 The control of thermal expansion represents a challenge in materials design. This work shows that the length of the lattice parameter is a key element for controlling thermal expansion. By varying the lattice parameter through external pressure, chemical

Enhancement of the thermal expansion of organic charge transfer salts by strong electronic correlations [PDF]
, 2014 Organic charge transfer salts exhibit thermal expansion anomalies similar to those found in other strongly correlated electron systems. The thermal expansion can be anisotropic and have a non-monotonic temperature dependence.

Thermal expansion, electrical conductivity and hardness of Mn3Zn0.5Sn0.5N/Al composites
Science and Engineering of Composite Materials, 2018 Mn3Zn0.5Sn0.5N/Al composites were successfully prepared by sintering at 623 K and 723 K. It is found that the thermal expansion of Al is effectively decreased with the addition of negative thermal expansion material Mn3Zn0.5Sn0.5N, which plays the role ...

Experimental Study on Thermal Expansion Behavior of Concrete under Three-Dimensional Stress
Advances in Civil Engineering, 2021 Concrete is widely used in underground engineering and bears three-dimensional stress transmitted by overlying load. When a fire occurs, the thermal expansion of concrete structure under such stress state is different from that under stress-free state ...
