The complete stress-strain curve of rock is divided into pre-failure and post-failure regions according to the peak stress.
岩石的应力—应变全过程曲线以峰值应力为界,通常分为破坏前区和破坏后区两部分。
补充资料:磁窑堡窑
磁窑堡窑 中国西夏的瓷窑。窑址在宁夏灵武县磁窑堡。西夏时期开始生产烧造白瓷、青瓷、黑瓷、褐釉瓷、茶叶末釉和酱红釉瓷等。种类包括生活用具、文房用具、娱乐用具、雕塑艺术品和建筑材料,如碗、盘、盆、馂、杯、盒、壶、罐、缸、瓮、灯、铃、帐钩、白瓷瓦等。以刻花、剔花、印花、雕塑、绘彩等技法作出装饰。风格属中原的磁州窑类型。生活用具又表现出明显的民族特点。该窑到元代继续生产。明清时期烧粗瓷大碗,规模小,工艺不精,已处于衰落状态。 |
