Evaluation of Polymer Fatigue Strength and Durability

This research article evaluates the effects of fatigue loading and manufacturing artifacts on the strength and durability of NORYL™ 731 polymers. It highlights the significant differences in fatigue life between single and dual-gate injection molded samples, emphasizing the importance of fatigue testing in material selection and product development. The findings reveal that dual-gate samples exhibit a drastically reduced fatigue life compared to single-gate samples, underscoring the need for ear
