Transmission and reflection of waves at structural junctions connecting thin orthotropic plates

Abstract We present a semi-analytical method for computing the reflection and transmission coefficients at joints connecting an arbitrary number of semi-infinite orthotropic plates based on line-junction approximation. use wave approach describe reflection, mode conversion between eigenmodes vibro-acoustic equations plates. A detailed derivation is presented here first time meeting junction without restrictions orientation principal material axes both with respect to in different The discussed two specific example configurations, namely L- T-shaped plate junction. Furthermore, scattering rib-stiffened are derived, occurrence resonance phenomena discussed.
