Load contribution plots

Load contribution plots let you optimize the flow of loads, applied to the critical regions of your model, with respect to damage and static failure. After you identify where the model fails and when the most damaging events occur, you need to know the loads that contributes the most to the local damage. When you identify the loads that provoke the largest damages, you can refine the flow of loads to the critical regions. The Function Definition (SDF) scenario provides the following load contribution plots. For more information, see Specialist Durability Function Definition scenario.

Load contribution to damage plot

This plot displays the relative decrease of the damage at a selected position if a load is omitted.

Example:

In this plot, load 3 contributes the most to the local damage on node i. To track the damage value due to each load, you can use the Fine Tracking command. In this example, the damage becomes approximately 2514.1 times larger when load 3 is included in the calculation. Load 1 has the second most significant influence. On the other hand, loads 2 and 5 have quite beneficial influences. If node i is the critical region of the component, you must decrease the influence of load 3 to the critical region to improve the durability behavior.

Load contribution to stress plot

Example:

Similarly, you can plot the local contribution for the maximum of Von Mises stresses to optimize the flow of loads with respect to static failure:
