| Abstract(J) | 従来、自動車衝突安全性能FEM解析において、薄板鋼板のき裂進展をソリッド要素で予測するには、計算コスト増大といった課題があった。 今回、破断可能性が高い部分のみを自動的にシェル要素から詳細ソリッド要素に変換し、かつサブサイクリング法の適用により上記課題を解決し、き裂進展を再現出来る技術を確立した。 Translation |
| Abstract(E) | Conventionally, in FEM analysis of crash safety performance of automobile, there has been a subject such as an increase in calculation cost in order to predict crack propagation of a thin metal sheet by solid element. This time, we have established a technology that can solve the above subject and reproduce crack propagation by automatically converting only the part with high crack possibility from the shell element to the detailed solid element and applying the sub-cycling method. |
