Calibration and Validation of Multiscale Model for Ultimate Strength Prediction of Composite Laminates Under Uncertainty
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A methodology to account for the effect of epistemic uncertainty (regarding model parameters) on the strength prediction of carbon fiber reinforced polymer (CFRP) composite laminates is presented. A three-dimensional ...
Robust Resource Allocation for Calibration and Validation Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Model calibration and validation are two activities in system model development, and both of them make use of test data. Limited testing budget creates the challenge of test resource allocation, i.e., how to optimize the ...
Time Dependent System Reliability Analysis Using Random Field Discretization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel and efficient methodology for timedependent system reliability analysis of systems with multiple limitstate functions of random variables, stochastic processes, and time. Since there are ...
A Single Loop Kriging Surrogate Modeling for Time Dependent Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current surrogate modeling methods for timedependent reliability analysis implement a doubleloop procedure, with the computation of extreme value response in the outer loop and optimization in the inner loop. The computational ...
Resilience Assessment Based on Time-Dependent System Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Significant efforts have been recently devoted to the qualitative and quantitative evaluation of resilience in engineering systems. Current resilience evaluation methods, however, have mainly focused on business supply ...
Adaptive Surrogate Modeling for Time-Dependent Multidisciplinary Reliability Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Multidisciplinary systems with transient behavior under time-varying inputs and coupling variables pose significant computational challenges in reliability analysis. Surrogate models of individual disciplinary analyses ...
Sensitivity Analysis of a Bayesian Network
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a Bayesian network (BN), how a node of interest is affected by the observation at another node is a main concern, especially in backward inference. This challenge necessitates the proposed global sensitivity analysis ...
Bayesian Network Learning for Data-Driven Design
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bayesian networks (BNs) are being studied in recent years for system diagnosis, reliability analysis, and design of complex engineered systems. In several practical applications, BNs need to be learned from available data ...
Time-Dependent Reliability Analysis Using a Vine-ARMA Load Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A common strategy for the modeling of stochastic loads in time-dependent reliability analysis is to describe the loads as independent Gaussian stochastic processes. This assumption does not hold for many engineering ...
Big Data Analytics in Uncertainty Quantification: Application to Structural Diagnosis and Prognosis
Publisher: American Society of Civil Engineers
Abstract: This study investigates the use of big data analytics in uncertainty quantification and applies the proposed framework to structural diagnosis and prognosis. With smart sensor technology making progress and low-cost online ...
