/MAT/LAW112: 紙、段ボール材料向けの異方性弾塑性材料の例題: ソリッド編
始めに 以前、こちらに、入力パラメータの少ないシェル向けの設定方法を理解するための例題を投稿しました。 今回はソリッド要素向けの設定方法を例題を通して理解していきましょう。シェル編と同じように 弾性材料としての設定 降伏応力を追加する（応力拡大はまだしない） 降伏応力の拡大効果を追加する という順番でやっていきます。 例題モデルの共通部分の説明 今回は、このように 8 要素用意し、それぞれ異なる試験をします。図内の X,Y,Z は全体座標系です。このモデルは、全体座標系の XYZ が材料方向 123 とそれぞれ同じ向きになっています。 文字で読むよりも、こちらのアニメーションを見る方が、早いでしょう。(変形倍率は 10倍です。)…

Pin Bearing Test (Composites) Radioss Solver
Hi I am trying to do a very simple pin loaded test according to the ASTM standards in composites using Radioss. I have modelled my composite with MATLAW25 and PCOMPP property. For the pin, i use MATLAW1 and PSHELL property. To establish contact between the two i use INTER 7. I use IMPVEL to move the pin at 200 mm/min…

Why it is not showing stress value for the nodes which shares it with multiple components ?
When I try to measure stress value(stress plot) through Measure —> Nodal Contour for the nodes after isolating any particular component which shares nodes with some other components will not show stress value instead it will show NA. If you try the same scenario in the old version like 2019,2021 or 2022 it will work…

/MAT/LAW112 紙・ダンボールなどの材料の例題: シェル編
始めに 紙の箱や段ボールに使われている材料を模擬するための弾塑性材料 /MAT/LAW112 を用いたシェル 1要素モデルの例題を示します。 シェル向けの方が、入力項目が若干すくないため、まずシェルの例題を作りました。ソリッドの例題はまた別記事とします。 ぱっと見、/MAT/LAW112 はややこしいですので、次の順番で少しずつ理解を深めていきましょう。 （線形）弾性特性の定義 降伏応力拡大のない、塑性の定義 降伏応力が拡大する、塑性の定義 例題モデルの共通の部分の説明 例題モデルはこのように要素が 6個あり、材料方向1 の配向角 0 度と 90度の物に対して、それぞれ、5% の引張、圧縮、せん断試験を行います。…
