A Numerical Ductile Failure Simulation Technique Based on Phenomenological Damage Concept

수치해석을 이용한 현상학적 연성파괴 모사 기법

This paper proposes a simple numerical method to simulate ductile failure behaviors. The method is based on finite element analysis with a simple damage theory. To validate the proposed method, simulated results are compared with experimental data. Despite its simplicity, the proposed method well predicts experimental results systematic analyses are also performed to investigate the effect of the element size.
