Numerical investigation of the basilar membrane vibration induced by the unsteady fluid flow in the human inner ear [PDF]
Archive of Mechanical Engineering, 2020 For a deeper understanding of the inner ear dynamics, a Finite-Element model of the human cochlea is developed. To describe the unsteady, viscous creeping flow of the liquid, a pressure-displacement-based Finite-Element formulation is used.

Model-free Data-Driven Computational Mechanics Enhanced by Tensor Voting [PDF]
Computer Methods in Applied Mechanics and Engineering, 2020 The data-driven computing paradigm initially introduced by Kirchdoerfer and Ortiz (2016) is extended by incorporating locally linear tangent spaces into the data set. These tangent spaces are constructed by means of the tensor voting method introduced by
