“…Fundamental expression of the Tresca is also used as failure criterion for structures under various loads together with the von Mises formulation. Historically, the Tresca was considered more fundamental, but the von Mises was seen more appealing for convenient approximation [12]. Similar works have used the von Mises as found in [4,13] which lead this work to observe Tresca contour.…”

The remarkable influence of the global warming to Arctic environment opens a possibility to conduct a voyage from Asia to Europe through the Northern Sea Route (NSR). This option is considered as a decent solution to reduce fuel consumption and increase time efficiency in delivering cargo to the designated destination. However, this alternative comes with a challenge to keep safety of ship structures against an impact with obstacles which are possibly encountered at the Arctic. Solid ice can be considered as a serious threat to the double bottom of ship structures in impact phenomena, especially ship grounding. In this work, a series of grounding calculations are conducted to produce estimation of structural crashworthiness during interaction between double bottom and conical type ice. Material characteristics based on tensile testing of polar class material are applied to calculation and compared with non-polar steel.

“…This material is suitable for nonlinear analysis in which the observation subject experiences remarkable destruction in a plastic state while the time-dependent match the dynamic characteristics in the collision. Pioneering work [30] in impact engineering has considered the plastic-kinematic model for ship material, and it is judged satisfactory in representing overall structural behaviour under impact.…”

This paper presents an analysis of the side hull in marine steel structures under accidental collision phenomena. The type of side collision considered in this work is where the striking ship penetrates the struck ship. First, the configuration of the collision phenomenon is defined, including the ship geometry, mechanical properties of the material, and applied parameters. The collision scenarios are built by applying external dynamic parameters, including target location and striking velocity. Impact locations are determined on three different regions of the struck ship's side hull: the fore-end, middle-hull, and after-end regions. These are discussed, followed by results based on the applied velocity. Second, the tendency of the collision energy is evaluated to observe the structural behaviour on the struck ship's side hull during penetration by the striking ship. Progressive failure is summarised based on the results of two parameters, and f the material model is confirmed by comparing the collision energy with pioneering work on ship collision.

The safety of ship under collision has been developed in terms of navigational and structural aspects. These efforts are aimed to provide more safety from the internal part of a ship. However, in a collision, the external dynamics also needs to be considered, for instance velocity and location. In this study, these parameters are applied and observed regarding on a series of ship-container collision scenario. A freight container is used in the first stage and behaviours such as internal energy and effective stress are summarized. An alternative design so called buffer container is presented to offer better protection to a liquid cargo. The second stage is started by applying similar collision scenario as the first stage to the buffer container and comparing structural behaviour of this analysis. It is obtained that leakage possibility can be reduced on the buffer design as the strength has become approximately twice better than the freight container.
