【 摘 要 】

Destruction of welds in metalwork is caused, in most cases, by low-cyclic fatigue. Among the wide spectrum of existing fatigue gauges, the Integral Strain Gauges are widely adopted in practice of experimental researches of different machine parts and carrying systems of vehicles. The paper proposes a new method based on finite element analysis of calibrating dependence establishment for ISG placed on the weld material by the use of few welded specimens of special geometrical shape providing the obtainment of several points of the calibrating curve in the tests process. Calibrating dependences allow determining the stress value σxin places of accumulated fatigue damages concentration which is used for serviceability estimation of welded joints by traditional techniques.
