Description Capability of a Simple Phenomenological Constitutive Model for High-Strain-Rate Plasticity Data

간단한 현상학적 구성방정식의 고속 유동응력 기술 능력

A recently reported simple phenomenological constitutive model (SK) demonstrated comparable or better data description capability to/than one of the rigorous and physics-based models, the PTW model. The simple SK model is believed to be an efficient model for practical applications where an extensive computation is needed, and can serve as a rigorous comparison standard for the development of a physics-based model.
