Measurements with thermoelastic technique from infrared microscopy on random trabecular structures

In this paper it is proposed a measurement technique based on differential thermal microscopy based on the application of a thermoelastic measurement system and an infrared zoom optics to analyze stress distribution on a random lattice structure realized by stereolitographic additive techniques. Lattice structures, because of the possibility to be actually easily realized by additive manufacturing techniques, see a growing interest and a lot of application in engineering and medical fields. The possibility to experimentally analyze stress conditions by new full field and non-contact measurement techniques is fundamental to correctly design components made of it, predict its life, optimize performances.
