Abstract
A hybrid three-dimensional boundary element normal mode expansion technique is developed to study the guided wave scattering from an arbitrary shape defect in a plate. Lamb wave incident into a circular through plate hole was studied as an example. The scattered wave displacement field and its normal mode component are given. Mode conversion from Lamb wave to SH wave at the defect boundary were observed.
