普通のシェル要素に対するフリー寸法最適化の例題
始めに 本記事では、普通のシェル要素 (PSHELL) に対するフリー寸法最適化 (DSIZE) の例題です。 例題 ダウンロード: https://us.v-cdn.net/6038102/uploads/11KLKPC35H5W/model01.7z 解析モデル自体は 100x100x板厚 mm に対する、片持ちばりです。板厚はフリー寸法最適化 (DSIZE) が決めます。単位系は ton, mm, s で行きます。 材料は E=2e5MPa, nu=0.3, ρ=8e-9 ton/mm^3 の鉄相当です。 最適化の条件は、次の通りです。最適化の設定自体は本記事の主眼ではないので、モデルをみてください。 コンプライアンス上限 1.4mJ…

接着モデル材料 /MAT/LAW116 の 1要素例題、その1
はじめに 本記事では接着をモデル化するのに便利な /MAT/LAW116 材料を使った 1要素モデルの例題を示します。本材料は、速度依存性がありますが、本例題では、速度依存性は扱いません。もしかしたら、例題その２で扱うかもしれません。 /MAT/LAW117 という LAW116 よりも設定項目の少ない簡単な材料モデルもあるので、そちらも参考にしてください。 材料を扱うときは、線形→塑性→ダメージや破断という順番で扱っていくとわかりやすいと思うので、本例題も 3部構成になっています。 例題はどれも、10x10x1mm のヘキサ要素を 1mm 引っ張り上げる試験となっています。…

/MONVOL/AREA で空間の体積を出力する例題
始めに モニター体積の中で /MONVOL/AREA は体積 (と袋の面積) の出力に特化したカードです。これ自体は、一切、解析に影響を及ぼさないため、体積を監視したい袋状の物に対して気軽に使うことができます。 例題 ダウンロード: https://us.v-cdn.net/6038102/uploads/454L04E6QDGM/model01.7z 10x10x10mm の箱を引っ張って体積を変えるだけの例題です。 どのモニター体積にも共通ですが、袋を作るシェルの法線は、外側を向いている必要があります。 /MONVOL/AREA の書式は簡単で、袋を作るサーフェスを指定すれば完了です。…
