A component is loaded by mechanical load or temperature load. The Q400 - DIC system measures e.g the strain distribution on the component surface. The measurements can be used to localize "hot spots" and to compare with FEM analysis. DIC gives the engineers a powerful tool to optimized components in terms of mechanical loading. This leads to component strength increasement and product cost reduction due to more efficient mechanical structures.
