Abstract

The aim of the present study is to develop and validate an efficient boundary element method approach for solution of in-plane, time-harmonic problems in elastodynamics that involve finite elastic solids weakened by holes of different shapes. The modeling approach is within the framework of continuum mechanics and linear wave propagation theory. The results obtained show a sensitivity of both the dynamic stress concentration factor and the scattered wave field that develop in the finite solid to defect geometry, to wave interaction with the holes and to multiple hole interaction.
