TL;DR: In this paper, an analytical failure criterion is proposed to characterise ship plated structures manufactured with aluminum or steel materials subjected to low impact velocities, and the criterion considers the critical deflection, force and absorbed energy of plates laterally impacted by a hemispherical indenter, and assumes that failure occurs at the presence of necking.

TL;DR: A review of experiments and calculation procedures for the resistances of ship structural components subjected to impact loadings is presented to highlight the importance of large-scale collision and grounding experiments and to discuss the technical difficulties and challenges in analytical, empirical and numerical analyses.

TL;DR: In this paper, a small-scale stiffened plate specimen is quasi-statically punched at the mid-span by a rigid indenter, in order to examine its energy absorbing mechanisms and fracture.

TL;DR: In this paper, experimental and numerical results of drop weight impact test are presented, on the plastic behavior and fracture of rectangular plates stuck laterally by a mass with a hemispherical indenter.

TL;DR: The outcome of the study is a discussion and recommendations regarding mesh size, failure criteria and damage models, interpretation of material data and how they are used in a constitutive material model, and finally, uncertainties in general.
