A 巻: 70 号: 691 ページ: 377 - 382キーワード：概要：The objective of this study is to apply the element-free Galerkin method (EFGM) to the dynamic crack problem for evaluating dynamic fracture mechanics parameters. The EFGM is first applied to a stationary crack problem under dynamic loading. Then we apply the EFGM to a generation phase problem of dynamic crack growth. Both results obtained from the EFGM analysis are compared with those of the FEM analysis using a very fine finite element mesh or the moving singular element technique. It is found that the EFGM analysis has enough accuracy both for a stationary crack problem under dynamic loading and for a dynamic crack problem, compared with the FEM analysis. Moreover, the EFGM has the advantage of selecting arbitrary integral paths or moving integral paths for the J-integral without restriction of elements in the EFGM.抄録：英語フィールド
