**Force lines**method is used in Solid Mechanics for visualization of internal forces in a deformed body. A force line represents graphically the internal force acting within a body across imaginary internal surfaces. The force lines show the maximal internal forces and their directions.

But stress in a solid body is a tensor not a single vector. What is the relationship between force lines and the stress tensor field? If I know the force lines can I calculate the stress tensor field? If I know the stress tensor field can I calculate the force lines?
