RISUncertainty Analysis for Time- and Space-Dependent Responses With Random Variables
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The performance of a product varies with respect to time and space if the associated limit-state function involves time and space. This study develops an uncertainty analysis method that quantifies the effect of random ...
Robustness Metric for Robust Design Optimization Under Time- and Space-Dependent Uncertainty Through Metamodeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Product performance varies with respect to time and space in many engineering applications. This paper discusses how to measure and evaluate the robustness of a product or component when its quality characteristics (QCs) ...
Physics-Based Gaussian Process Method for Predicting Average Product Lifetime in Design Stage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The average lifetime or the mean time to failure (MTTF) of a product is an important metric to measure the product reliability. Current methods of evaluating the MTTF are mainly based on statistics or data. They need ...
Adaptive Kriging Method for Uncertainty Quantification of the Photoelectron Sheath and Dust Levitation on the Lunar Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an adaptive Kriging based method to perform uncertainty quantification (UQ) of the photoelectron sheath and dust levitation on the lunar surface. The objective of this study is to identify the upper and ...
