粒子モデル統合破壊解析システムFRAXSTの開発と展開

抄録

In order to prepare input data efficiently, we focused on Peridigm, a destructive analysis system published on open source, and developed an integration support tool FRAXST using open source tools and Python. By utilizing FRAXST, it was possible to automatically create data files manually, so conversion errors are eliminated and the working time can be drastically reduced, and the use of random numbers disturbs the arrangement of particles and initial irregularities It was also possible to add. Moreover, by incorporating Cython which is an expansion module of Python, we further aimed at faster data conversion. In addition to data conversion, it is possible to set material properties and boundary conditions with easy operation by linking with GUI. In order to verify the effectiveness of FRAXST, we verified by using the example of collisional fracture analysis of flat plate and confirmed the difference between crack propagation due to reproduction of fracture phenomenon of flat plate and initial irregularity.
