AB  - Plane-strain fracture toughness is one of the main parameters in linear elastic
fracture mechanics and its purpose is to show the material capability to withstand load while
having a defect. Main validity aspect for such an assessment is to provide a wide enough crack
front to enable plane-strain condition. Nonetheless, in FDM (Fused Deposition Modeling)
polymers, due to structural anisotropy caused by material properties and Additive
Manufacturing (AM) process parameters, more validity aspects must be met. During the planestrain fracture toughness test a crack must follow a straight line from initiation cite up to the
point of structural failure. For such a purpose a DIC (Digital Image Correlation) device can be
used for crack path direction analysis. Plane-strain fracture toughness assessment is conducted
according to the ASTM D5045-14 standard for testing of polymer materials. Tests are
performed on SENB (Single Edge Notched Bend) specimens, made from two similar polymer
materials: quasi-brittle PLA and ductile PLA-X composite. Specimens are manufactured with
four different AM process parameters, i.e., layer height, infill density, printing orientation and
one batch was dried before testing. Testing is conducted using 3-point bending test fixture on
universal testing machine, with DIC dual-camera device placed ahead of the machine in order
to capture full-field deformations of front SENB specimen surface (Fig. 1).
