The degradation model for composite materials with interval uncertainties is a mathematical
representation of the residual properties in the degradation process. And validation …

Statistical model improvement consists of model calibration, validation, and refinement
techniques. It aims to increase the accuracy of computational models. Although engineers in …

Due to inherent variability (ie, aleatory uncertainty) in material properties, loading conditions,
manufacturing processes, etc., simulation output responses should follow certain …

This study addresses the challenge of equifinality in agent-based modeling (ABM) by
introducing a novel sequential calibration approach. Equifinality arises when multiple …

Uncertainty is an inherent characteristic that objectively exists throughout various stages of
engineering structures, such as manufacturing and service, which significantly affects the …

With nonlinearity and uncertainty existing in engineering problems, it is important to predict
the probability distribution of a response of an engineering model. The probability …

Probability distributions of responses have been widely used in structural analysis and
design because of their complete statistical information. In practice, the dimensionality of …
