Development of a Framework for Modelling Adhesive and Bulk Fracture in Ice: Application to Electroexpulsive Ice Protection Systems

ABSTRACT

This study proposes a modelling framework for ice adhesive and bulk fracture. In this framework, adhesive and bulk fracture mechanisms are treated as distinct phenomena. Adhesive fracture is modelled using the well‐established cohesive zone model, which is widely used in the analysis of composite material delamination. Conversely, bulk fracture is treated using bond‐based peridynamics, a relatively new theory that is becoming increasingly popular for modelling brittle material failure under impact conditions. The contribution of this study is the assessment of the combination of these models for impact‐driven ice failure. A test rig was designed and manufactured to validate the modelling framework against experimental results. An analysis of the two modelling methods was performed to identify the necessary model parameters, and numerical values specific to ice failure were proposed. Although they overestimate the delaminated area, the simulations reproduce the main features of the observed fracture patterns. Ultimately, a sensitivity analysis of the framework to variations in model parameters demonstrates areas for enhancement.
