The model is based on the Lodge-Yamamoto network theory and is an extension of the Phan-Thien-Tanner model, with a kinetic process in which specific forms of creation and destruction rates are assumed. The final equation is simple with a small number of empirical parameters required and can be conveniently employed in engineering simulations. The predictions based on the model in a variety of shear and oscillatory shear flows are given. The stress response obtained from the model prediction agrees well with experiments on both shear and oscillatory flow histories. © 2020 Author(s).||Source Title:||Physics of Fluids||URI:||https://scholarbank.nus.edu.sg/handle/10635/189640||ISSN:||10706631||DOI:||10.1063/5.0033199|
