研究了磁流变液在大范围磁场强度下的拉伸行为，并将其分为4种类型，提出了归一化的拉伸应力和归一化的磁场强度。结果显示，通过对拉伸应力和磁场强度的归一化处理，清楚地显示了不同磁场强度下的应力-应变曲线类型，可以利用下降的磁场效应和加强的结构效应来估算和比较磁流变液在不同磁场强度下的拉伸行为。根据拉伸行为的改变，发现拉伸屈服应力与磁场强度的关系指数随着磁场强度的增加而增大。
Tensile characteristics of magnetorheological (MR)fluids under tension tests over a wide applied magnetic field have been studied.Four tensile behaviors of MR fluids have been described.Normalized tensile stress and the normalized magnetic field have been proposed.The results showed that by normalizing tensile stress and magnetic field,the nature of the stress-strain curves under different initial magnetic fields during the elongations.By the electric field effect and the particle structure effect,the tensile characteristics of MR fluids under different conditions can be well compared with each other on the elongations.The exponent of tensile yield stress versus magnetic field was found to increase with magnetic field.
