Fatigue Life Prediction for Cyclic Loaded Textiles
topic
Textile fatigue life modelling fits S-N curves relating cyclic stress amplitude to median cycles to failure using log-linear regression on fatigue test data, incorporating statistical scatter through Weibull analysis at each stress level to generate probabilistic S-N curves specifying failure probability as a function of both stress level and cycle count for design and specification purposes.
Role
Predicts the probabilistic fatigue failure behaviour of load-bearing textiles in cyclic applications including climbing ropes, parachute lines, and medical sutures, enabling design engineers to specify minimum fatigue life with quantified probability of survival under defined loading spectra representative of actual service conditions.
