Entwurf einer Unterrichtsmethodikes is reported. A short-term method for measuring the slow crack growth was successfully developed and applied, and a crack has been observed via microscopy. It was observed that a large plastic zone is formed in the specimen before the crack initiation and also ahead of the crack tip.作者: anthropologist 時間: 2025-3-23 12:35
