No.472 Torsional Failure Simulation of Brittle Material using Adaptive Solid to SPH

例題153の解析モデルに ADAPTIVE_SOLID_TO_SPH 機能を追加して脆性破壊のねじり試験解析を行いました。破壊したソリッド要素からSPH要素が飛び出して飛散物として計算が続行されます

Keywords: SPH, ADAPTIVE SOLID TO SPH, debris simulation, MAT_ADD_EROSION, ERODING_CONTACT,LS-DYNA R11

Tool: LS-PrePost ver.4.6, LS-DYNA MPP Single Precision Win64 R11

なお，本事例はサンプルであることをご了承下さい。
