SINT Technology is a specialized residual stress laboratory and a residual stress analyis centre.
The constant analysis and monitoring of residual stresses, allows to preserve mechanical components and materials from possible fractures or malfunctions in time.
Residual stresses, indeed, limit the loading capacity and safety of those components during operation and in some cases it is neccesary to be able to quantify those stresses. Actually, residual stresses, can be casual or desiredand could involve also polymeric materials and composite materials
Turbine blades and other metal components are often built with internal residual stresses to limit cracking and fatigue. In those cases, it is necessary to perform strong controls and careful calibrations to determine the desired level of stress during the production
In the case of polymeric materials, residual stresses concern in particular the surface: their presence can cause a failure of the material and its permanent deformation.
