Probabilistic Aspects of Fatigue
Fatigue damage accumulation is a stochastic process that results in considerable variability in the durability of all structures and components. Sources of this variability include customer usage, material properties, component geometry and manufacturing processes. Modeling errors introduce additional uncertainties in any fatigue assessment.
This seminar with Dr. Socie will provide tools and techniques for determining the risk of failure and identifying the major risk contribution factors.
About the Seminar
Traditional deterministic modeling captures the basic physics of a process but ignores the variability and the uncertainty. Statistical analysis captures the variability and the uncertainty but ignores the physics. Probabilistic analysis includes both the physics and the variability of the process.
Deterministic variables in an analysis are replaced by random variables, each one described by a statistical distribution. This results in an assessment of the risk of failure. In addition, the probabilistic analysis tools identify major contributing factors to this risk so that effort can be focused on controlling factors with the greatest influence on product reliability. Basic probability and statistics are reviewed in the seminar before discussing the various statistical analysis methods.
The seminar provides extensive test data to establish typical variability in all of the parameters. This test data is then used in case studies and example problems. Finally a new tool called the Fatigue Calculator is described. This web-based tool will enable seminar participants to immediately begin using probabilistic fatigue analysis.
