Thermal Expansion in a Glass and Aluminum Window: Part 1

2018-02-21T10:38:23-08:00

Equipment designers must accommodate thermal expansion (CTE)of dissimilar materials, especially when they are subject to large temperature changes.  This problem is often called "CTE mismatch."  In this blog, we give the fundamentals of thermal expansion calculations used in thermo-mechanical analysis. These calculations are simple but [...]
