Residual stresses are a series of forces that modify the stability of a component by changing the resistance to fatigue and to fracture. Residual stresses can be found in plastic materials, composite materials or polymeric ones.
SINT Technology is an Italian Company that provides analysis and diagnostic services applied to residual stresses, vibration, noise, gas emissions and the thermodynamic performance of machinery.
As a specialized residual stress laboratory, SINT Technology has developed a specific system for measuring residual stress via the hole drilling method: it is called MTS3000 – Restan which is fully compliant to ASTM E837-13 standard.
MTS3000 – Restan is able to measure residual stresses into metals and other kinds of materials, with standard drilling speed of about 400,000 rpm: this avoids introducing any other residual stress into the material during the test process. Also plastic, composite and other kinds of materials can be tested, both in the lab and on site.
For residual stress measurements by hole drilling method, SINT Technology is also accredited test lab, in accordance with ISO/IEC 17025.
