constant-deformation tests 解釋
定變形試驗
  • constant : adj 1 恆定不變的,固定的,穩定的,恆久的;繼續不斷的。2 不屈不撓的,堅韌的。3 忠實的,有節操的。n...
  • deformation : 變形,走樣
  • tests : 抽查
  1. The experimental results is shown as followings : ( 1 ) the cyclic flow stress - strain curves in an incremental step test could be expressed as the power law relation : ( 2 ) when the strain amplitude is lower during cyclic deformation tests under constant strain control, softening firstly appears, then gradually hardens with the increasing numbers of cycle ; when the strain amplitude is higher, hardening firstly appears, then gradually softens

    試驗結果表明: ( 1 )循環流變應力與應變的相互關系曲線均符合冪律關系式: ( 2 )在室溫下進行恆應變幅循環變形過程中,當所控制的應變幅較小時,該材料首先出現循環軟化,之後隨循環周次的增加直至循環失效前該材料出現了硬化現象。當應變幅較大時,該材料開始出現硬化,然後隨循環周次的增加才出現軟化。
