Establishing an oblique impact breakage master curve using a DEM bonded contact model

This paper aims to establish a breakage master curve of oblique impact using DEM bonded contact model. Despite numerous advantages particle by DEM, there exist two major issues in hindering the distinct power with fully predictive capacity. The first barrier is notable discrepancy probability evaluation, i.e. ratio experiments and damage DEM. second lack an model where subject various angles can be unified. In this work, these longstanding barriers are addressed conducting digital twin A newly developed used account for effect angle. equivalent velocity proposed shown successfully remarkable all angles.
