How far does the reinforcement zone extend?

Explanation:
Reinforcement around openings is added to smooth the transition in thickness and reduce stress concentration at the edge of the hole. The rule specifies that this reinforcement zone must extend a distance equal to two times the opening diameter from the edge. Since the opening has diameter d, the reinforcement extends outward by 2d. This helps distribute the stresses around the opening rather than concentrating them at the boundary. Smaller extensions would not adequately relieve the concentration, while much larger extensions would be more conservative than required. So the reinforcement zone extends 2d.
