Abstract
In recent decades, the interest of the manufacturing industry towards additive manufacturing techniques has increased considerably. Speed and ease of implementation are just some of the factors that helped making this type of production one of the most developed in the world, considering also the possibility of creating complex geometries. The present research uses of a series of Al A357 specimens produced by SLM method. The experimental measurements on a first geometry have been used to calibrate the ductile damage model implemented in the FE code. The material model is based on both classical incremental model of plastic response with isotropic hardening and phenomenological concept of damage in continuum mechanic. The result of the calibration process was verified through the comparison of FE simulation of reticular specimens with the measured experimental response. Comparison between experimental data and numerical results will be discussed.
