Wave motion in finite and infinite media using the Thin-Layer Method
The Thin-Layer Method (TLM) is a semi-analytical technique that is efficient for wave propagation problems involving partially heterogeneous media. While the method has been used widely for horizontally stratified media, e.g. dynamic response of foundations over layered soils, there remain many …
