Gaussian copula is used to measure and recover correlation among states and parameters before and after sharing. Preliminary validation using several hypothesized specimens illustrates that our approach. can improved the accuracy in parameter calibration, leading to improved diagnosis and prognosis. Further validation on complex structures with complicated damage growth mechanisms is left as future work by the authors.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.eucass.eu\/doi\/EUCASS2023-095.pdf\">Read the full paper here<\/a><\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>X.
