ABSTRACT
Nowadays, many researchers related to the naval area study the behavior of steel when it is subjected to great deformations, including fracture, presenting criteria to evaluate different structural configurations of the different areas of the ship. In the present paper, we will use a fracture criterion formulated from a representative volume of element (RVE) model, which considers aspects of triaxiality for its formulation. The RVE considers micro voids that help to classify the triaxial state of the material and is subjected to different triaxial states before being formulated. Furthermore, this fracture criterion is evaluated in a collision of a typical stiffened plate on one side of the ship and a rigid bow bulb, obtaining different areas of severe damage as the bulb speed is varied. Complementarily, values of the history of triaxiality during the collision, and effective deformation of fracture are obtained.
