コメント

  1. この破壊モデルは、結合材料/MAT/LAW59 (CONNECT)とのみ適合性があります。
  2. 破壊基準:

    ソリッド要素の破壊は、変位値が基準に達したとき、または内部エネルギーが破壊内部エネルギー値に達したときに発生します。

    Ifailで制御される連成または非連成破壊定式化は、互いに排他的となります。変位基準とエネルギー基準は、同時に使用できます。両方のエネルギー基準を同時に使用できます(別々に両方の方向のEImaxおよびエネルギーに基づく)。

  6. 面積は、ソリッド要素の上下のサーフェスの平均値として計算されます。実際の面積が、初期面積にAREAscale係数を掛けた値に到達すると、要素全体が削除されます。結合要素に接合した要素が破壊すると、このオプションは、結合要素の大変形による節点のシューティングを防止するために使用できます。
