The Bingham model is generally used to describe the flow of cement-based materials, and its parameters, such as yield stress and plastic viscosity, are measured using a rheometer. However, the rheological measurement does not provide the unique Bingham parameters for a single material when rheometers take different rheological geometries or measuring protocols. This study constructs a model that can yield the ideal Bingham parameters with the rheological measurement. We first introduce the generation of an ideal domain strictly following the Bingham equation, and then an unsupervised domain adaptation by adversarial training makes it possible to match the rheological measurement with the ideal Bingham parameters. The proposed model is applied to the experimental data measured with mortar samples, where the measurements for a single sample are conducted by three different measuring protocols. The resultant (ideal) Bingham parameters are identical regardless of the protocols used.

通过使用 Bingham 方程的对抗性训练确定的无偏流变特性
宾汉姆模型通常用于描述水泥基材料的流动,其参数(如屈服应力和塑料粘度)使用流变仪测量。然而,当流变仪采用不同的流变几何结构或测量协议时,流变测量不会为单一材料提供唯一的 Bingham 参数。本研究构建了一个模型,该模型可以通过流变测量产生理想的 Bingham 参数。我们首先引入了严格按照 Bingham 方程生成理想域,然后通过对抗训练进行无监督域适应,从而可以将流变测量与理想的 Bingham 参数相匹配。所提出的模型适用于用砂浆样品测量的实验数据,其中单个样品的测量通过三种不同的测量协议进行。无论使用何种协议,生成的(理想)Bingham 参数都是相同的。
