Stress analysis on tensile loaded honeycomb sandwich structured material of poly lactic acid filament

In this study, an observation conducted on honeycomb sandwich structured material (HSSM). Research on honeycomb structure was already done to see the effect of geometry on the overall material characteristic. As it was already discovered in past research, a simulated result of 3D printed product is very close to the actual result. This research will be focusing on simulation on honeycomb sandwich composite material with tensile loaded in a uniaxial direction. This research employs finite element simulation to observe sandwich composite respond to a tensile load. The honeycomb structure was used as sandwich composite's core layer. The wall thickness to core layer thickness ratio of R1 = 1:3; R2 = 1:6; R3 = 2:3; and R4 = 2:6 was used in this research. The model was subjected to uniaxial load parallel (0°) to core plane. The simulation conducted with von-mises yield criterion resulting in different stress concentration location and magnitude indicated by red color as high-stress grading to yellow, green to blue as low stress. The result indicating that HSSM.
