The inverse finite element method (iFEM) is a model-based technique to compute the displacement (and then strain) field of structure from strain measurements and geometrical discretization same. Different literature works exploit error between numerically reconstructed strains experimental perform damage identification in structural health monitoring framework. However, only detection localization are performed, without attempting proper size estimation. latter could be based on machine...

Abstract In the past two decades, aerospace industry has massively shifted from aluminum-made components to composite materials such as carbon fiber reinforced polymers (CFRP), striving for more fuel efficient and lighter aircrafts. Consequently, traditional joints have been replaced by adhesive bonded interfaces, which are also most common choice repair damaged components. Although bonding is permanent connections, it not free of disadvantages: one failure modes, debonding laps, very...
Deflection monitoring plays a key role in bridge Structural Health Monitoring, as deflection data may offer valuable insights into potential structural issues, such cracks and corrosion. However, deflections under operative loads presents challenges, particularly scenarios where establishing fixed reference point for displacement sensors is impractical, when spans waterway or the be vulnerable to vandalism. In recent years, inverse Finite Element Method (iFEM) has emerged possible solution....
The inverse Finite Element Method (iFEM) has recently gained much popularity within the Structural Health Monitoring (SHM) field since, given sparse strain measurements, it reconstructs displacement of any beam or shell structure independently external loading conditions and material properties. However, in principle, iFEM requires a triaxial measurement for each finite element, which is seldom feasible practical applications due to both costs cabling-related limitations. To alleviate this...
Adhesive bonding is widely adopted in aeronautic structures to join composite materials or repair damaged substrates. However, one of the most common failure modes for this type joint debonding under fatigue loading. In past years, it has been proven that deboning quantification feasible, given abundant experimental data are available. context, using domain adaptation assist diagnostic tasks based on labeled from similar simulations would be thoroughly beneficial. methods designed...
