dc.description.abstractThe application of fused filament fabrication (FFF) process has been growing fast in different fields of industries as a practical and cost-effective solution for prototyping and production of functional components. However, the fracture behavior of the printed specimens is a subject of research as there is a need for service reliability and predictable performance of components. In this paper, the effects of internal architecture in FFF process on mixed-mode I/II fracture of U-notched printed samples were experimentally and numerically investigated. The load carrying capacity of U-notched 3D printed parts were calculated using a combined J-integral criterion and equivalent material concept (EMC) to consider the elastic-plastic behavior of the material. The tensile and fracture specimens were printed by biodegradable polylactic acid (PLA) thermoplastic filaments under constant filling ratio and at different filling patterns, namely, 3D infill, hexagonal, linear and triangular. The experiments were performed to determine the transversely isotropic mechanical properties and the fracture loadings of the samples at different loading angles. A finite element model was developed to conduct the J-integral calculation for each sample based on transversely isotropic properties of printed samples and plane-stress analyses. Based on the results, the samples with 3D infill structure possessed the lowest strength, load carrying capacity and fracture toughness as compared with that of other filling patterns. In contrast, the triangular filling pattern incorporated the highest fracture toughness and load carrying capacity in samples produced by FFF technique.
