INVENTOR: Lecon WOO TITLE: THERMOMECHANICAL ANALYZER ABSTRACT OF THE DISCLOSURE A thermomechanical analyzer is adapted to measure stress or spring in a sample material by the use of a flat, passive spring, having a known modulus of elasticity, in conjunction with an axially displaceable shaft which mechan- ically links the spring and the sample together. The linkage is such that the sample under test and the spring are mechan- ically connected in parallel, i.e., each undergo equal dis- placement. A transducer senses axial displacement of the shaft such that the magnitude of the shaft displacement is related to the stress in the sample. The sample may be sub- jected to temperature variations during the test cycle.
