【Autodyn】衝突現象における熱エネルギーについて

[hidechika.karasawa.74]

Autodynでの衝突解析結果において，プロジェクタイルおよびターゲットの運動エネルギーや内部エネルギー，塑性仕事の時間履歴が確認できますが，熱エネルギーの時間履歴は確認できるのでしょうか．

また，熱エネルギーの時間履歴が確認できる場合，その熱エネルギーの計算アルゴリズム・計算式はそのように実装されているのでしょうか．

ご教示頂けますと幸いです．よろしくお願いいたします．

The physical events Autodyn models usually have short-time duration in milli-seconds or micro-seconds. In such short time duration, energy transfer from thermal conduction is usually very small.

Thus, during impact analysis, thermal transfer between projectile and target is ignored in Autodyn analysis.

However, temperature change of a material due to plastic work can still be predicted by Autodyn if material specific heat is properly defined. Be aware that the change of temperature is caused by plastic work and has nothing to do with thermal transfer.
