The applicability of the Averaged Strain Energy Density (ASED) criterion [1] to predict the failure of notched Polylactide Acid (PLA) specimens fabricated by Fused Deposition Modeling (FDM) is validated by means of experimental data reported by Ahmed and Susmel [2], Difficulties when estimating the ASED control volume radius based on the measured fracture toughness are revealed and discussed, whereas the accuracy of the ASED criterion is found to be satisfying when a novel alternative approach is used to define the control volume size.
