The term trajectory describes the path along which an object moves in space. The flight path of a shot put and the orbit of a planet are examples of trajectories.
Results can also be displayed in the form of trajectories. These are vectorial representations that visualize the direction and size of the results. This representation is useful in order to understand the distribution of internal forces and stresses in a surface.
Modeling in RFEM
In the RFEM 5 program generation, you can define nodes of the "Trajectory" type. This requires the existence of a line which is used as a reference object for the description of the trajectory. By specifying the parameter δ, you can define the position of the node along the trajectory. 0% refers to the starting point, 100% to the end point of the trajectory.
Result Trajectories
For surfaces and solids, you can display the trajectories of the principal stresses by selecting the respective angle α for the top, middle, and bottom of the surface.
