Chair: Masaaki Tanaka (JAEA)

10:15 AM - 10:30 AM

[1B02] Failure mechanism under extreme loadings and prevention of catastrophic failure

(13)Study on mechanism of local failure with experiments and analysis

*Shigeho Kubota1, Shin Ogiso1, Takuya Satou1, Naoto Kasahara1 (1.Tokyo Univ.)

Keywords:large deformation elastic-plastic analysis, stress triaxiality, local failure, fracture curve

構造不連続部において発生の可能性が指摘されている局部破損のメカニズムは未だ十分には解明されていない。本研究では、局部破損のメカニズムを研究し、新たに破壊曲面の考え方を提案した。
