Webinar Series: Revolutionizing Simulation

Simulation Governance is Critical for Reliable Condition-Based (Predictive) Maintenance


This webinar will present a case study in which the goal was the development of a mathematical model for supporting condition-based maintenance (CBM) decisions. The model was designed for estimating the remaining fatigue service life of high-value mechanical components, given their service history and that specific flaws (such as corrosion defects) have been discovered in them, thus enabling CBM  to move damaged component removals from unscheduled to scheduled maintenance action.

The case study serves as an illustration of the universal process of model development in a setting of applied mechanics.  The formulation, calibration, validation, updating and documentation steps subject to the protocols of verification, validation and uncertainty quantification (VVUQ) will be covered. The ranking of alternative models with respect to their predictive performance will be addressed and the requirements for data management, and the process by which revisions are made and validated when new data become available, will be outlined.

What you will learn:

  • Mathematical models have both intuitive, creative components and objective, science-based components. These two components must be in equilibrium.
  • What is the difference between finite element modeling and numerical simulation?
  • What is the domain of calibration and how to specify it?
  • How the outcome of validation experiments should be evaluated and reported?
  • Why is the development of mathematical models open-ended? – Why no one can claim to have the last word?
  • Why simulation governance is essential for the success of numerical simulation projects?
