🔍 Key Concepts

• Stress concentration at sharp corners vs smooth curves • How crack tips behave under cyclic loading in steel structures • Differences between round vs square terminations in reducing localized stress

💭 Think About

• Which choice changes the shape of the crack end so that stress is spread out over a larger, smoother area? • Which option might actually make the crack tip sharper or add more rigid attachments that could increase local stress? • Think about how shipyards stop cracks temporarily before doing a full structural repair—what is the first, simple step they often take?

✅ Before You Answer

• Identify which options modify the geometry at the crack ends rather than just adding more weld or structure nearby • Ask which shape (round vs square, sharp vs smooth) gives lower stress concentration at the end of a defect • Consider whether adding welded brackets near a crack would redistribute stress smoothly or risk creating new hard spots and stress risers
