Negative thermal expansion materials: technological key for control of thermal expansion

open access: yesScience and Technology of Advanced Materials, 2012
Most materials expand upon heating. However, although rare, some materials contract upon heating. Such negative thermal expansion (NTE) materials have enormous industrial merit because they can control the thermal expansion of materials.

Numerical evaluation of expansion loops for pipe subjected to thermal displacements

open access: yesCurved 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 ...
