Villavicencio, R., Liu, B. and Guedes Soares, C. (2012), “Response of stiffeners with attached plate subjected to lateral impact”, Maritime Engineering and Technology, Guedes Soares et al. (Eds),Taylor & Francis Group, London, pp.393-398
The paper presents drop weight impact tests and finite element simulations examining the dynamic response of stiffeners with attached plate struck transversely by a mass. The influence of the impact velocity and the stiffener type is analyzed using the force-displacement responses of the impacted specimens. The numerical simulations represents the stiffener-plate weld joint using shell and solid elements. Good agreement is found between the finite elements simulations and the experimental results. The plastic response of the small-scale impact tests is used to predict the energy absorption of a typical full-scale ship bottom panel subjected to a minor grounding incident as a practical application of this work.
