Lamb waves occur in thin-walled structures in two wave modes?the symmetric and the antisymmetric mode. Their oscillation on the structures? surfaces is either in phase (symmetric) or shifted by a phase angle of ??
p
(antisymmetric). In this work, a meth...

Cold-formed steel (CFS) structures are widely used in construction and infrastructure due to their lightweight and high-strength properties. However, their thin-walled nature makes them geometrically sensitive to compressive loading. The Digital Twin (DT...

Aerospace thin-walled structures are susceptible to various forms of damage and they can be effectively inspected using Lamb wavefields. However, Lamb wavefields contain at least two dispersive modes which interfere with the generation of a clear image f...

In structural engineering, thin-walled structures play an important role in the design of the lightweight structural model. It carries different loading conditions when it exists in any model, and it is designed with thin plates or thin shells. Penetrati...
