摘要：

In this study, the mechanical behavior of high-density polyethylene (HDPE) reinforced with short natural fiber was evaluated using a test bench designed to monitor the high-cycle bending-fatigue characteristics of gear teeth. High-resolution imaging and acoustic emission (AE) were used to document crack initiation and propagation against the number of cycles for all specimens. Fatigue versus number of cycles was modeled using S-N curves, damage indices and a linearized Weibull distribution. Correlations between the variables are discussed and compared with published data. Crack progression, residual load, and AE show consistent results that track the progressive damage to the material.
