Modeling of Stress Distribution and Fracture in ABS, PLA, and Alumina-Filled PLA Filaments and FDM-Printed Specimens

In the presented work, a probabilistic approach to fracture analysis of commercially available polyacrylonitrile butadiene styrene (ABS) and polylactide (PLA) filaments fused deposition modeling (FDM)-printed tensile samples produced from them, as well PLA filled with alumina (Al2O3) specimens, is discussed. The results reveal presence symmetry between stress distribution in plastic–elastic regions. value transition point elastoplastic was established. It shown that probability density destruction bound state obeys Cauchy distribution. resulting model describes distributions minimum deviation 0.021% maximum 0.048% for ceramic–polylactide (60Al2O3/40PLA) filament.
