The Research on Visualization of Second Order Tensor Fields
二阶张量场可视化研究

Second-order tensors are widely existed in engineering, physical science and biomechanics. Examples are stresses and strains in solids and velocity gradients in fluid flows. This paper takes the Boussinesq's problem as an example which is typical in Elasticity Mechanics, and visualizes the second-order real symmetric tensor fields by ellipsoid icons and hyperStreamlines. The results are reasonable. The visualization methods adopted in this paper are also suitable for other second-order symmetric tensor fields such as electromagnetic field.
