A simple thixotropic–viscoelastic constitutive model produces unique signatures in large-amplitude oscillatory shear (LAOS).

Highlights: [•] We characterize a simple thixotropic–viscoelastic model using LAOS. [•] Asymptotically nonlinear LAOS provides a detailed yet low-dimensional fingerprint. [•] We present an analytical solution for the asymptotic nonlinearities. [•] LAOS achieves separation of thixotropic and viscoelastic timescales. [•] Model predicts ability to measure short thixotropic timescales with LAOS. [ABSTRACT FROM AUTHOR]
