Extension of the Pufem to Elastic Wave Propagation in Layered Media
Abstract eng: This work deals with the extension of the Partition of Unity Finite Element Method (PUFEM) to solve wave problems involving propagation, transmission and reflection in layered elastic media. Problems dealing with wave reflection at a free surface and propagation of pure Rayleigh waves are also considered. The proposed method consist to apply the plane wave basis decomposition to the elastic wave equation in each layer of the elastic medium and then enforce necessary continuity conditions at the interfaces through the use of Lagrange multipliers. The accuracy and effectiveness of the proposed technique is determined by comparing results for selected problems with known analytical solutions.
