machining strain 中文意思是什麼
machining strain
解釋
機械加工應變-
The method for measuring the plane strain fracture toughness klc has been introduce to high polymer bonded explosives ( pbx ) by systematically studying technologies concerning the shape of specimen, the depth and its machining of crack, the loading rate, the measurement of critical fracture load, and the computation of klc, etc. the method has been used to test and study klc of three typical high polymer bonded explosives which are j2, jl, j3 respectively both at normal temperature and unmoral temperature
本文以高聚物粘結炸藥為研究對象，對測試高聚物粘結炸藥的平面應變斷裂韌度所涉及的樣品形狀、裂紋深度及裂紋制備、加載速度、臨界斷裂載荷p _ q的確定及平面應變斷裂韌度k _ （ ic ）的計算等方面進行深入研究，建立了較為完善的炸藥平面應變斷裂韌度測試方法。
