Which mechanism caused increased structural weakness in Viking longships undertaking transatlantic voyages?

💡 Explanation

Cyclical fatigue led to weakness because repeated wave impacts induced stress concentrations at joints. Micro-cracks initiated and propagated with each cycle. This outcome occurred rather than corrosion or embrittlement, since fatigue accumulates incrementally, weakening the hull planking.
