One source of concern when strain gauging epoxy materials, is that if the gauges are continuously energised at high power densities, then the heat generated by the strain gauges will cause large apparent strains and will reduce the modulus of the underlying material. The magnitude and significance of the heating effect are discussed and methods of reducing this effect are indicated.
