This paper employs a discrete damped dynamic system to investigate the emerging concept
of a digital twin. Dynamic systems are well understood across engineering and science …

A novel method for characterising and propagating system uncertainty in structures
subjected to dynamic actions is proposed, whereby modal shapes, frequencies and …

Frequency response functions (FRFs) are important for assessing the behavior of stochastic
linear dynamic systems. For large systems, their evaluations are time-consuming even for a …

Polynomial chaos solution for the frequency response of linear non-proportionally damped
dynamic systems has been considered. It has been observed that for lightly damped …

This paper proposes a non-intrusive interval uncertainty analysis method for estimation of
the dynamic response bounds of nonlinear systems with uncertain-but-bounded parameters …

Due to the aggressiveness of the environmental factor, the variation of the dynamic load, the
degeneration of the material property and the wear of the machine surface, parameters …

Over the last decade, surrogate modelling technique has gained wide popularity in the field
of uncertainty quantification, optimization, model exploration and sensitivity analysis. This …

Probabilistic engineering mechanics aims to take into account uncertainties of input
parameters of models and evaluating their impact onto the model responses. For frequency …

The analytic approximation of dynamic responses is very significant for performing the
optimization, parameter identification and reliability analysis of structural systems. However …

The digital twin of a physical system is an adaptive computer analog which exists in the
cloud and adapts to changes in the physical system dynamically. This book introduces the …
