Numerical Modeling of the Ice-Conical Structure Interaction Process Using Element Erosion Technique

Abstract

Nowadays, the Finite Element Analysis method is widely used, including in the field of fracture mechanics, because to the grown of computing power. Numerical modeling of fracture mechanics is a developing method in the Ice-Structure Interaction field. One of the approaches to modeling ice failure is the Finite Element Method with Element Erosion Technique, which is widely used among researchers. However, the question of using a material model that most accurately describes the behavior of ice taking into account its physical and mechanical characteristics remains open. Also, researchers often overlook the question of the strain rate effect on the values of ice load. This article presents the results of numerical modeling of the interaction of level ice with a conical support of offshore structure. The dependences of the ice load value on the ice velocity are also presented and compared with the results obtained according to regulatory documents.
