A new approach for displacement and stress monitoring of tunnel based on iFEM methodology

Smart Materials and Structures, 2021
Abstract Structural monitoring plays a key role for underground structures such as tunnels. Strain readings are expected to report structural conditions during construction and at the final delivery of the works. Furthermore, it is increasingly requested an extension to long-term monitoring from contractors with possible use of the ...

Detecting Loosening of Bolt‐Flanged Pipe Using Smoothed Pseudo Wigner–Ville Distribution: Digital Twin‐Based Approach Using Convolution Neural Networks

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this paper, an integrated digital twin‐based fault‐diagnosis framework is proposed to detect bolt loosening in flanged pipe connections. The approach combines finite element‐based numerical modeling, experimental modal analysis, and advanced signal processing‐assisted deep learning to achieve reliable loosening detection under operational ...

Screening and Interventions for Elder Mistreatment: Geriatric Emergency Department Guidelines 2.0 Systematic Review

Academic Emergency Medicine, Volume 33, Issue 7, July 2026.
ABSTRACT Background Elder mistreatment is common, underreported, and associated with significant morbidity and mortality. Emergency department (ED) visits provide an important opportunity to identify elder mistreatment and initiate intervention, but the evidence for the impact of screening or intervention strategies in this clinical setting is not well

Toward to an Automatic Crack Size Estimation with iFEM for Structural Health Monitoring

, 2023
The inverse Finite Element Method (iFEM) is a model-based technique to compute the displacement (and then the strain) field of a structure from strain measurements and a geometrical discretization of the same. Different literature works exploit the error between the numerically reconstructed strains and the experimental measurements to perform damage ...
