Characterization of fatigue properties of 3D printed polylactic acid

Abstract

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