WebExpansion and CTE. One could argue that the standard type of thermomechanical analysis (TMA) tests, in which a very small load is applied to a sample, is really a subset of creep testing. Some vendors actually treat it as such in their dynamic mechanical analysis (DMA) software. However, TMA really needs to be addressed on its own for several ...
