| Abstract Scope |
Material fatigue data play a crucial role in product development, as demand for product optimization no longer allows unnecessary overengineering. To this day, the assessment of dynamic material properties is widely based on statistical approaches established long before the availability of significant computing power. Typical analysis methods such as Dixon-Mood, lifetime-stress regression require an arbitrary definition of acceptable durable load levels as a percentile of the load capacity distribution. Limitations in capturing the variability of real-world scatter behavior with such methods further reduces the quality of the fatigue performance assessment.
The Fatigue Limit Model (FLM) utilizes a 5-parameter modeling approach, describing load dependency of cycles to failure - including a failure-free load level, as well as variable scatter behavior. This presentation outlines the benefits and potential limitations of this numeric approach. A software solution is introduced for easy implementation into a typical engineering and test lab environment. |
