Isogeometric Analysis of Fracture Problem (Second Report)

- Simulation of Ductile Crack Propagation for Automobile Crash Analysis -

Abstract

We propose computational procedures for treating fracture problems in Isogeometric Analysis (IGA). In this study, we introduce an algorithm for analyzing ductile crack propagation. The proposed algorithm determines the propagation direction and simulates the propagation process. We validate the effectiveness of our method by comparing crack propagation analyses to tensile experiments using thin high-tensile steel specimens.
