Paper Abstract

When a Rectangular tension test specimen made of carbon steel undergoes yield stress on the occasion of a tensile test, striped patterns or `Stretcher Strains' appear on the surface affected. These patterns are easily discernible by the naked eye. Thus the patterns function as a visual sensor for yield stress. In order to utilize this phenomenon as a yield stress sensor one need only polish the surface to a fine smoothness. In the following the basic data on the use of `Yield Stress Patterns' or Stretcher Strains as a yield stress sensor will be presented. An example will be put forth in order to make an analysis of the use of yield stress patterns as a stress sensor.
