...Weifei Hu; Jiquan Yan; Feng Zhao; Chen Jiang; Hongwei Liu; Hyunkyoo Cho; Ikjin Lee A mature digital twin (DT) is supposed to enable engineers to accurately evaluate the real-time reliability of a complex engineering system. However, in practical engineering problems, reliability analysis (RA) often...

...Xiaonan Lai; Xiwang He; Yong Pang; Fan Zhang; Dongcai Zhou; Wei Sun; Xueguan Song The concept of digital twins is to have a digital model that can replicate the behavior of a physical asset in real time. However, using digital models to reflect the structural performance of physical assets usually...

...Michael G. Kapteyn; Karen E. Willcox This work develops a methodology for sensor placement and dynamic sensor scheduling decisions for digital twins. The digital twin data assimilation is posed as a classification problem, and predictive models are used to train optimal classification trees...

...Paromita Nath; Sankaran Mahadevan This paper proposes a detailed methodology for constructing an additive manufacturing (AM) digital twin for the laser powder bed fusion (LPBF) process. An important aspect of the proposed digital twin is the incorporation of model uncertainty and process...

... in real time to ensure that it works under the designed load capacity. In this study, we developed a lightweight digital twin by the multifidelity surrogate (MFS) model to improve the real-time monitoring and prediction accuracy of the structural safety of a crane boom. Digital twin technology, which can...

...Shuo Wang; Xiaonan Lai; Xiwang He; Yiming Qiu; Xueguan Song Digital twin has the potential for increasing production, achieving real-time monitor, and realizing predictive maintenance by establishing a real-time high-fidelity mapping between the physical entity and its digital model. However...

...Weifei Hu; Yihan He; Zhenyu Liu; Jianrong Tan; Ming Yang; Jiancheng Chen Precise time series prediction serves as an important role in constructing a digital twin (DT). The various internal and external interferences result in highly nonlinear and stochastic time series. Although artificial neural...
