撕裂紋 的英文怎麼說
中文拼音 [sīlièwén]
撕裂紋
英文
torn grain-
Tearing mode crack
撕開型裂紋Calculations of tearing energy of different crack depths and different loads have been done for double shear testpiece with interface cracks. at last, the relationship between tearing energy and crack depth has been given, so has the relationship between tearing energy and load
根據有限元結果計算出不同裂紋深度、不同載荷下的撕裂能，分析了試件的撕裂能與裂紋深度與載荷的關系。The cracks extend along the matrix / strengthening - phases interfaces and form the cleavage steps and tear ridges. there appear some very small dimples on the fracture surfaces of the directionally solidified samples, which come from the nb - based solid solution particles in the big plates of the strengthening phases, but no dimples on the fracture surfaces of the as - cast sample. it can be concluded from above results that niobium - niobium silicide based in - situ composites ( rmics ) with a uniformly orientated microstructure can be produced by the ebfzm with high temperature gradient, and their mechanical properties can be increased
隨著抽拉速率的提高和硅化鈮強化相間距與尺度的減小，材料的室溫拉伸強度和斷裂韌性均有提高， _ b最高可達778 . 4mpa ， k _ （ ic ）達到了46 . 3mpa ? m ~ （ 1 / 2 ） ；試樣的拉伸斷口基本表現為脆性解理斷裂的花樣，裂紋沿基體強化相界面繞過強化相進行擴展，在裂紋擴展方向存在解理臺階，並形成撕裂棱。
