Saad-Eldeen, S., Garbatov, Y. e Guedes Soares, C. (2016), “Experimental investigation on the residual strength of thin steel plates with a central elliptic opening and locked cracks”, Ocean Engineering, Vol. 115, pp. 19-29

This work investigates the residual structural capacity of experimentally tested steel plates with a large central ellipsoidal opening with and without locked cracks, subjected to uni-axial compressive load. A series of experimental tests have been carried out. The tested plates were a part of a real box structure, which represents a scaled midship section of single hull tanker ship, exposed to a corrosive seawater environment. A plate with one large opening with different crack lengths is analysed. The effect of the combined effect of the plate opening and different crack lengths on the residual strength is investigated. The experimental results; force-displacements relationships, dissipated energy, stress-strain relationships, resilience and toughness are presented and analysed. Several important plate locations are studied and the stresses are estimated and analysed. The collapse modes are discussed and the ultimate strength and strain have been compared with other experimental results of plate with different opening sizes published in the open literature.
