Peridynamic framework to model additive manufacturing processes

Kurzfassung

This paper introduces a novel framework for analyzing additive manufacturing processes. By employing a peridynamic mesh-free implementation, it overcomes certain limitations encountered with finite element-based approaches in regard to defects and fractures. The framework includes the implementation of thermodynamical material behavior and a novel boundary detection algorithm, as the outer surface area will undergo changes during the manufacturing process. The proposed methods are thoroughly validated, and a comprehensive example is provided as a demonstration.
