Abstract(J) | 高圧タンクのCFRPの破壊メカニズムを理解することは重要と考える.本研究では,CFRPの損傷特性と積層厚さを考慮した3Dソリッド要素を計算モデルとして用い,CFRP の剛性低下を表現する損傷進展解析を実施した.線形FEM解析と本手法との比較により,高圧タンクの破裂メカニズムの解明を試みた. Translation |
Abstract(E) | It is important to understand the CFRP fracture mechanism of high-pressure vessels. In this study, we used 3D solid elements that take into account the damage characteristics and stacking thickness of CFRP as a calculation model, and performed damage progression analysis that express the decrease in the rigidity of CFRP. The fracture mechanism of high-pressure vessel is discussed by comparing the linear FEM analysis with this method. |
