Recent work modeling the rheological behavior of thixo-elasto-viscoplastic (TEVP) materials such as human blood indicates that it has all of the hallmark features of a complex material, including shear-thinning, viscoelasticity, a yield stress, and thixotropy. After decades of modeling steady-state human blood rheological data, and the development of simple steady-state models, like the Casson and Herschel–Bulkley, the advancement and evolution of TEVP modeling to transient flow conditions now has reinvigorated interest. Using recently collected human blood rheological data, over a wide range of flow conditions from steady state to various oscillatory shear flows, we show and compare modeling efforts with the original and a viscoelasticity-enhanced version of the enhanced Apostolidis–Armstrong–Beris (EAAB) model. The viscoelasticity enhancement is then justified by its ability to improve predictions of small and large amplitude oscillatory shear as well as uni-directional oscillatory shear flow. The new viscoelastic parameter is then incorporated into a methodology to estimate the viscoelastic time scale of human blood. Lastly, we compare our new TEVP modeling approach with another recently developed TEVP model, mHAWB, for context.

对触变性-弹-粘塑性（TEVP）材料（例如人血）的流变行为进行建模的最新工作表明，它具有复杂材料的所有标志性特征，包括剪切稀化，粘弹性，屈服应力和触变性。经过数十年的稳态人体血液流变学数据建模，以及简单的稳态模型（例如Casson和Herschel-Bulkley）的发展，TEVP建模到瞬态流动条件的发展和演变现在引起了人们的兴趣。使用最近收集的人类血液流变学数据，在从稳态到各种振荡剪切流的各种流动条件下，我们展示了建模工作，并将其与增强的Apostolidis–Armstrong–Beris（EAAB）的原始版本和粘弹性增强版本进行了比较模型。然后，通过其改善小振幅和大振幅振荡剪切以及单向振荡剪切流的预测的能力来证明粘弹性增强。然后将新的粘弹性参数合并到一种方法中，以估算人体血液的粘弹性时间尺度。最后，我们将新的TEVP建模方法与另一个最近开发的TEVP模型mHAWB进行了比较。
