1.	Li Yi, Mitsuteru Asai, Bodhinanda Chandra, Masaharu Isshiki, Energy-tracking impulse method for particle-discretized rigid-body simulations with frictional contact, Journal of Computational Particle Mechanics, https://doi.org/10.1007/s40571-020-00326-5, 2020.04, 剛体接触解析を行う常套手段としては、バネとダッシュポットで簡易的に表現するペナルティ法が良く採用されるが、時間増分が小さくなる、また人工パラメータの設定方法が曖昧であるなどの、問題点があった。そこで、適切な力（撃力：インパルス）で接触を表現するインパルス法に着目し、特にエネルギー保存性を担保できるEnergy-tracking impulse法をベースとし、これをDEMなどの粒子離散化された剛体の解析へと適用した。.
