Abstract

Experimental evaluation of mechanical behaviours through full-field non-contact techniques is useful in order to properly design components and to validate their numerical models. In this paper stress and strain distributions on trabecular structures are experimentally investigated through Digital Image Correlation and Thermoelastic Stress Analysis. Finite elements model is computed and a comparison with experimental results is given in order to obtain a reliable predictive numerical model. The method wasappliedtoatrabecularstructureobtainedbytopologyoptimizationandrealizedboththroughstereolithography and fused deposition modeling.
