- 中文摘要: 本文是利用有限單元法以電算機來模擬針壓潛變試驗。以求得壓針進入試樣的穩定速率和試樣彈性係數,針在試樣中的起始深度等的關係。同時本文亦比較以Tresca有效應力取代Von Mises有效應力時對針速的影響,計算結果是以兩種有 效應力所得的針速相同。
- 英文摘要: The modulus and depth effects of the steady state impressing velocity in the impression creep test are examined by the finite element method based on a single power law constitutive equation for the deformation of each and every element. The results obtained by using the Von Mises stress and by using the Tresca stress in power law constitutive equation are found to be the same.
