Derivation and experimental analysis of the relation between temperature and stress.

- Abstract
The relation between stress and temperature in polymer composite materials was derived based on the energy conservation law. For the qualitative experiment, glass-fiber-reinforced plastic specimens were heat treated to produce surface strain, thereby completely releasing the stress in the material. The presence of surface distortion qualitatively confirmed the relation between stress and temperature, thereby confirming the underlying physical mechanism of the relation. A case study was undertaken to measure the surface strain for quantitative confirmation of the relation between temperature and stress. This study established the equation based on physical parameters for the quantitative measurement of the relation between the temperature and the stress and strain. Despite the experimental error, objective and meaningful experimental results can be obtained using our measurement approach for a variety of composite materials.
