Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques
This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture mat...
