Scaling of Shear Band Fracture Processesom replica scaling. Here the model is outlined briefly, with emphasis on the nucleation process which is the main contributor to rate effects. Then a series of calculations are described in which a range of strain rates was applied. The number and size of bands and the strain to failure are examined as a function of strain rate.作者: antenna 時(shí)間: 2025-3-22 03:44

Observations by transmission electron microscopy are used to relate microscopic to macroscopic behavior. Results show that cell size influences the strain rate sensitivity and may be a cause of history effects.作者: Oratory 時(shí)間: 2025-3-22 06:16 作者: SOBER 時(shí)間: 2025-3-22 10:02
