Abstract
This paper is the second of three papers on a refined internal strainwire technique. This paper examines the effect of internally embedded single-strand strainwires, both as reinforcing and as heating elements within a matrix material. To investigate possible reinforcing effects, two identical plates, one containing internal wires and the other without these wires, were examined. The photoelastic-fringe patterns (isochromatics) were photographed to determine if the presence of the wires causes an alteration of the isochromatic patterns. An investigation of the possible heating effects was accomplished in the same way, only, in this analysis, voltage was passed through the internal gages. To learn more about the heating characteristics of the wire-matrix system, the voltage in the gages was increased until the heating effect manifested itself. Using this technique, it was possible to determine the upper limit of applied voltage. The long-term effects of the applied voltage were also examined.
