Efficient simulation of elastic guided waves interacting with notches, adhesive joints, delaminations and inclined edges in plate structures

摘要

Highlights?An approach to model guided wave propagation in plate structures is presented.?The interaction of guided waves with notches, edges, delaminations and joints is simulated.?Only line elements are reqired to discretize the structure’s thickness direction.?Boundary conditions can be applied on the plate surface without requiring discretization.?CPU times are typically reduced by 2–3 orders of magnitude compared to a full finite element discretization.AbstractThis paper presents an approach to model transmission and reflection phenomena of elastic guided waves in plates. The formulation is applied to plate structures containing notches, inclined edges, delaminations or (adhesive) joints. For these cases, only the thickness direction of the structure needs to be discretized at several locations, while the dir
