  "abstract": "Fatigue tests conducted on elastomers inherently exhibit significant variability. Aging may induce stiffening and embrittlement, leading to premature failures outside the specimen gauge length and resulting in right‐censored data. Combined with the limited number of specimens, this leads to large uncertainties in fatigue lifetime estimation. This paper presents a survival analysis strategy to propose a probabilistic prediction of elastomers' fatigue lifetime during aging. The approach explicitly accounts for censored data and incorporates aging effects through material descriptors such as crosslink density. A Weibull parametric model and a semi‐parametric Cox regression model with a frailty term are considered. Application to an experimental dataset shows that both models provide consistent predictions within the range supported by the data, while the Cox model offers increased flexibility by handling multiple aging‐related covariates without prescribing a baseline distribution. The proposed framework complements Weibull‐based approaches and provides a practical tool to quantify fatigue failure probabilities under data‐limited aging conditions.",
