Simple Stress Sensor: Utilizing of Stretcher Strains


This article concerns an attempt to utilize stretcher strains to determine the stress concentration factor in the elastic-plastic state of steel strip specimens having semicircular notches. The dangerous section of steel gear tooth profiles is also brought under examination. In both cases, the utilization of stretcher strains provides successful results. For this undertaking, the observation of the striped pattern was made solely by the naked eye, without the use of a measuring instrument.

The examples shown will illustrate that the use of stretcher strains is a simple and convenient stress sensor.
