Which structural weakness was inherent in early ironclad warship construction using wrought iron plates?

💡 Explanation

When wrought iron plates were bolted, delamination occurred because of non-uniform stress distribution at the interface of layered constituents, creating microscopic fissures that grow under stress. Therefore, delamination results, rather than galvanic corrosion, wave-induced fatigue, or shell deformation, which involve different failure mechanisms and material properties.
