The term trajectory describes the path along which an object moves in space. The flight path of a shot put ball or the orbit of a planet are examples of trajectories.
Results can also be represented in the form of trajectories. These are vectorial representations that visualize the direction and magnitude of the results. This representation is helpful for understanding the distribution of internal forces and stresses in a surface.
Modeling in RFEM
In the RFEM 5 program generation, nodes of the type "trajectory" can be defined. This requires the existence of a line, which serves as a reference object for describing the path curve. The position of the node along the path curve can be determined via the parameter δ. 0 % corresponds to the starting point, 100 % to the endpoint of the path curve.
Result Trajectories
For surfaces and volume elements, the trajectories of the principal stresses can be displayed by selecting the respective angle α for the top, middle, and bottom sides of the surface.
