Thermomechanical analysis (TMA) is a thermal analysis technique that measures dimensional changes at a micrometer scale, such as deformation, in a material’s properties against time or temperature ...

All materials, with some exceptions, expand when they are heated. However, the amount of expansion per degree change in temperature varies depending on the substance. Since structures are made up of ...

Part one of this series, published in the January 2007 issue, discussed how to use linear superposition in the steady-state analysis of multiple heat-source systems. However, linear superposition also ...
