“…There are many works on experimental testing of colliding ships [263][264][265][266][267][268][269][270]. In all of them, the ships are scaled-down, sometimes significantly (1/45 [263], 1/35 [267], and 1/100 [268] scaled models).…”

“…What really jumps out from these works is the difficulty in realizing the experimental tests. For example, in order to estimate the energy involved in low energy collisions, Hagiwara et al [264] simplify the model manufacturing by omitting some structural members, which invalidates the experimental results. Also, nonsimilarities in material failure appear.…”

Similitude theory allows engineers, through a set of tools known as similitude methods, to establish the necessary conditions to design a scaled (up or down) model of a full-scale prototype structure. In recent years, to overcome the obstacles associated with full-scale testing, such as cost and setup, research on similitude methods has grown and their application has expanded into many branches of engineering. The aim of this paper is to provide as comprehensive a review as possible about similitude methods applied to structural engineering and their limitations due to size effects, rate sensitivity phenomena, etc. After a brief historical introduction and a more in-depth analysis of the main methods, the paper focuses on similitude applications classified, first, by test article, then by engineering fields.

“…The majority of researchers have focused on deriving the resultant damage of the ship collisions via analytical, experimental, and finite element methods. Hagiwara et al [2] proposed a method for predicting low-energy ship collision damage based on experiments and determined the initiation of plate fracture. Cho and Lee [3] developed a simplified method for the prediction of the extent of damage of stiffened plates due to lateral collisions.…”

The paper describes the simulation of impact loads applied on plate panels with welding-induced residual stresses and deformation (WSD). Numerical simulations using FEM are carried out to study the influence of welding-induced residual stresses and deformation on the impact strength of plate panels. Welding is simulated using a three dimensional thermal mechanical coupled finite element method. The welding stress and deformation are taken as the initial imperfections in the impact strength analysis and their influence on the behavior of plate panels subjected to impact loadings. The impact loadings from the three directions, the lateral direction and two in-plane directions of the plate panels are studied. Results show a certain reduction in the impact strength due to the existence of welding stress and deformation in the plate panels. It is found that the reduction of impact force is strongly influenced by the welding deformation and the impact directions in the plate panels. This reduction is more significant when the impact force is in the lateral direction.

“…The EPS criterion uses a maximum equivalent plastic strain value associated with the material failure, equation (3). This criterion was commonly used in ship to ship collision modeling [10,11] to described energy absorption due to structural collapse, given that the maximum plastic strain is dependent on the mesh size, load application and structural part localization.…”

“…The study of the structural behaviour of ships during a ship collision event using reduced scale model is not a common study in the ship research community [2]. The large quantity of structural details of a ship structure is one of the principal difficulties to overcome when working in a reduced scale; some aspects such as non-similarity in material failure and omission of structural member to simplify a scaled construction have significant influence in the results [3].…”

Abstract. Scaled models are important in naval engineering since actual ship size makes too expensive to test prototypes. However, the analysis of ship collision events employing naval structures in reduced scale is not an ordinary ship research area. The aim of this work is to create the basis for a posterior similarity study by analysing reduced scale ship structures submitted to impact loads. Two basic naval structures, commonly found in the construction of large ships, were considered for this study: a T cross-section beam submitted to a midspan impact test and a double plate panel with inner cross reinforcement also submitted to a central impact load. These models were made in a reduced scale of 1:100. The experimental material characterization was also carried out in this work, including the evaluation of the stress strain curve under quasi static conditions, the strain rate sensitivity and the structural failure using three criteria developed particularly for numerical modelling of ship collision by other authors.
