Contactless stress and strain measuring techniques for experimental optimization of additive manifactured components

Additive manufacturing is recently finding applications in industrial manufacturing of new mechanical components allowing the realization of new products with new processes. These new production processes represents an alternative to machining, casting or other classical productions, with significant benefits for low numbers series, for components of high cost or requiring high mechanical performances, and generally for small size components.


Some recent applications are the production of metal bone protheses, turbine blades, burner components for aircraft engines, components of internal combustion engines for racing cars and motorcycles.


In this lesson some full field measurement techniques of stress and strain distributions on components realized by this new production techniques are illustrated. The goal is to introduce new experimental methods and measurement techniques to optimize their structural and general performances.
