/VISC/LPRONY で超弾性材料に粘性を与える例題
はじめに Radioss には /VISC/LPRONY というカードがあり、超弾性材料に粘性を簡単に与えることができます。 何が簡単かと言うと、もともとの材料モデルが持つ剛性に対する割合で、粘性を決めることができるからです。 いつもなら、簡単な入力項目の説明をしてから、モデルの説明をするのですが、この材料は、この Form の部分がとてもややこしいので、結果を見てから理解を進めていきます。 Form=2 の例 ダウンロード: Form=1 は使える材料タイプが限られているため、制限のない Form=2 から始めます。 １要素モデルで、動的な引張試験をします。動的というのは、時刻 0 から、いきなり 100N を与えます。 /VISC…
