Sparse Regression for Discovery of Constitutive Models from Oscillatory Shear Measurements
Sachin Shanbhag, Gordon Erlebacher
We propose sparse regression as an alternative to neural networks for the discovery of parsimonious constitutive models (CMs) from oscillatory shear experiments. Symmetry and frame…

The Method of Harmonic Balance for the Giesekus Model under Oscillatory Shear
Shivangi Mittal, Yogesh M. Joshi, Sachin Shanbhag
The method of harmonic balance (HB) is a spectrally accurate method used to obtain periodic steady state solutions to dynamical systems subjected to periodic perturbations. We adap…
