Barré de Saint-Venant principle

The Barré de Saint-Venant principle states that, in structural mechanics, the effects of localized loads on a structure diminish with distance from the load. In simpler terms, when a force is applied to a specific point or small area of a beam or other structure, its influence on the structure decreases as you move away from that point. This means that you can analyze the overall behavior of the structure without needing to consider every detail of the load's application, focusing instead on broader, more significant effects in distant areas.
