Static component (SC) generation of guided waves (GWs), which combines the high
sensitivity of acoustic nonlinearity to micro-damage and low attenuative effect, has great …

In this paper, the generation of quasistatic pulses (QSPs) of guided waves propagation in
fiber reinforced plastic (FRP) thin plates is investigated. Numerical perspective of the …

In composite structures cyclic loading leads to micro-structural damage even at an early
stage. This damage grows over lifetime and may finally cause catastrophic failure. In this …
