Thermal Expansion in a Glass and Aluminum Window: Part 1

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

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 useful, and easy enough to perform by hand or with a spread sheet. For more complicated shapes, one must use computer modeling.  As an example, we perform a finite element analysis (FEA) in a later blog http://glewengineering.com/thermal-expansion-in-a-glass-and-aluminum-window-part-2/, of a glass and aluminum window and frame to show where the stress is excessive.  This points to the obvious need for a gasket to perform as a thermal interface material, in order to lessen [...]
