An interpolation method for coupling non-conforming patches in isogeometric analysis of vibro-acoustic systems

This paper presents an interpolation method for coupling non-conforming Non-Uniform Rational B-Splines (NURBS) patches in isogeometric analysis of vibro-acoustic systems. This coupling method is based on a master–slave formulation, in which a smooth interpolating function is first constructed to represent the sound pressure field of the master side and then is sampled to determine the discrete sound pressure of the slave side. The coupling...
