RISTreating Epistemic Uncertainty Using Bootstrapping Selection of Input Distribution Model for Confidence-Based Reliability Assessment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Accurately predicting the reliability of a physical system under aleatory uncertainty requires a very large number of physical output testing. Alternatively, a simulation-based method can be used, but it would involve ...
Reliability-Based Design Optimization Using Confidence-Based Model Validation for Insufficient Experimental Data
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conventional reliability-based design optimization (RBDO) methods assume that a simulation model is able to represent the real physics accurately. However, this assumption may not always hold as the simulation model ...
Framework of Reliability-Based Stochastic Mobility Map for Next Generation NATO Reference Mobility Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A framework for generation of reliability-based stochastic off-road mobility maps is developed to support the next generation NATO reference mobility model (NG-NRMM) using full stochastic knowledge of terrain properties ...
Confidence-Based Uncertainty Quantification and Model Validation for Simulations of High-Speed Impact Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Validation exercises for computational models of materials under impact must contend with sparse experimental data as well as with uncertainties due to microstructural stochasticity and variabilities in thermomechanical ...
