Characterization of fatigue properties of 3D printed polylactic acid

The goal of this research is to determine how tiredness behavior may be measured (PLA). A To variety technical data sets were S-N curves chosen and statistically re-analyzed. as described in the following section, generate a negative reference value reverse slope also an improved tolerance limit 106 2 failure cycles. average effect stress on fatigue can indicated via administering highest level achievable during cycle, according experimental examined after treatment.Furthermore stress/strength study effectively performed until printing orientation seems possess minimal influence PLA's general behavior. carried out taking into account. homogeneous, linearly elastic polymer described. When acceptable findings are not available, paper explains conduct evaluation (with survival probability better than 95%). demonstrates do so utilizing standard with negative-inverse regression 5.5 (2 cycles failure) equivalent 10% material's maximum σ_t.
