Abstract

Based on an equivalent analysis model, the dispersion equations of guided waves in 2D lattice sandwich plate are derived, and the dispersion curves calculated. A finite element model is also built according to the real structure of 2D lattice. Propagation of guided waves in hexagonal lattice sandwich plate is simulated using ABAQUS software. It is demonstrated that the equivalent analysis model can well describe the guided waves propagating along the whole sandwich plate at low frequencies.

Key words： dispersion curve; guided wave; lattice sandwich plate
