A simple dynamic model of monobloc concrete railway sleepers of non-uniform cross-section has been derived by reference to experimental data for about the first six resonance frequencies of 12 different types of sleeper. It is demonstrated that a sleeper is well modelled as a uniform Timoshenko beam

## Abstract By using boundary shape optimization on the end part of a semi‐infinite waveguide for acoustic waves, we design transmission‐efficient interfacial devices without imposing an upper bound on the mouth diameter. The boundary element method solves the Helmholtz equation modeling the exteri
