始めに こちらの記事では TN が厚さ方向の最大応力、TT が横手方向の最大応力、という説明を行いました。 ただし、実際には、TN にも TT にも未達なのに、応力が低下していてしまうことがあります。 どうしてそれが起きるのかを示すのが本例題です。 例題 ダウンロード: 1x1x1mm のヘキサ要素モデルです。この材料は、要素長に材料特性が依存するのでややこしいのですが、これ例題ではややこしい部分を考えなくて良いように、単位長さ 1mm を要素サイズとしています。 このように、厚み方向にも横手方向にも 1mm ずつ伸ばす条件です。 ヤング率/長さである EN=ET=1.0MPa/mm で、最大応力 TN=TT=1.0MPa ですので、双方に…
The FlightStream Self-Paced Training Presentation is a comprehensive resource designed to help users of all experience levels master aerodynamic simulation at their own pace. This training covers everything from the basics of FlightStream, including its interface and physics theory, to advanced topics like multi-body…
PhysicsAI를 사용하기 위해선 H3D 확장자의 해석 결과 파일이 필요합니다. Hvtrans를 사용하면 지원되는 해석 결과 에 한해 H3D 파일로 변환할 수 있습니다. 해당 스크립트는 사용자가 지정한 경로 및 파일 확장자에 대해 확인하여 Hvtrans를 배치 모드로 실행하는 스크립트입니다. 한번에 많은 양의 해석 결과 파일을 H3D 파일로 변환하고자 할 때 사용할 수 있습니다. 사용 방법: py 파일을 텍스트 편집기로 열어 아래의 내용을 수정하고 저장 hvtransPath : hvtrans가 설치된 경로 지정 path : 해석 결과 파일이 위치한 최상위 폴더 경로 지정…
Overview: In engineering and manufacturing, the durability of parts is a critical factor that directly influences the safety, performance, reliability, and cost-effectiveness of products. Determining how long a component can function under specific conditions without failure is essential for ensuring product longevity,…
INTRODUCTION Developing a lunar lander is a challenging task, as the Odysseus lander proved. Landers must be lightweight, while withstanding the stresses of the rocket launch and landing. Under ideal conditions, the lander would achieve zero velocity both vertically and laterally as the vehicle touches down. Practically,…
Overview: Adjusting suspension angles is crucial for optimizing vehicle handling, tire wear, and overall performance. The ability to customize the camber, caster, and toe angles of your suspension effectively can be the difference between first or last place when it comes to motorsport. For this purpose, a modified front…
始めに 本記事では、円筒座標系を使った異方性材料の例題を示します。 利用するカードは、まず、材料に直交異方性材料の MAT9OR, https://help.altair.com/hwsolvers/ja_jp/os/topics/solvers/os/mat9ort_bulk_r.htm 円筒座標系に CORD2C https://help.altair.com/hwsolvers/ja_jp/os/topics/solvers/os/cord2c_bulk_r.htm 要素プロパティに PSOLID です。…
Overview: Tooth brush model with Tooth brush motion in the global coordinate system and relative motion for the brush itself (rotation and pressure on the tooth). Brush wires deformation and contact pressure on tooth can be analysed. Release Version: Radioss v2025.0 Model:
始めに /INTER/TYPE25 のこちらの図を見ると、シェル要素の仮想オフセットサーフェスの角部を丸めていそうです。 https://help.altair.com/hwsolvers/ja_jp/rad/topics/solvers/rad/inter_type25_starter_r.htm 本例題では、本当にそうなっているのかを確認します。 例題 ダウンロード: このようなモデルです。 左上のばねは、仮想オフセット面に最初からつらつらの状態です。それより右側の部分がどうなっているのかを、この例題で調べましょう。この図は HyperMesh の 3D 表現ですので、Radioss がこうであるというわけではありません。…
Overview: When using the Relative Wear Model, EDEM calculates two geometry custom properties: Normal Cumulative Contact Energy and Tangential Cumulative Contact Energy. This script uses EDEMpy to add these two properties together and creates a new geometry custom property called Total Cumulative Contact Energy…
