Introduction to Uncertainty Quantification for Engineers

Feb. 22 - 1:00 to 2:00 PM CST
Part of the Mechanical Engineering Magazine Webinar Series
Presented by Dr. Mark Andrews, SmartUQ UQ Technology Steward
Dr. Andrews is responsible for advising SmartUQ on the industry’s UQ needs and challenges and is the principal investigator for SmartUQ’s project with Probabilistic Analysis Consortium for Engines (PACE) developed and managed by Ohio Aerospace Institute (OAI). Before SmartUQ, Dr. Andrews spent 15 years at Caterpillar.

Anyone who builds complex, mission critical systems knows that real-world performance is hard to simulate and test. This is due to uncertainty. It may arise from approximations or variations in boundary and initial conditions in models, or deviations in materials, assembly, operating conditions, and wear in finished products.

Uncertainty Quantification (UQ) tools can quantify these uncertainties while sigificantly reducing the number of simulations or tests required needed to get meaningful results. UQ tools help engineers analyze the difference between models and real world performance so they avoid premature failure, costly warranty payments, and emergency redesigns.

Using case studies and SmartUQ software for illustration, this webinar will introduce and demonstrate:

  • Knowledge of common UQ and probabilistic methods
  • How to apply UQ methods to an engineering system
  • How to use UQ techniques to drastically save design time
  • How to develop a robust and reliable design with UQ techniques
  • How to interpret UQ results when making decisions
