However, they become solid-state under a sudden strike or impact. And when the strike or impact is removed, the STFs can turn back to their equilibrium properties. This paper provides a detailed review on relevant literature related to the applications with shear thickening fluids. It introduced the factors affecting shear-thickening behaviour including volume fraction, particle size, particle shape, carrier fluid viscosity, temperature and some other factors.展开更多
