| 5 | A NEW METHOD TO DETERMINE THE R-CURVE OF CERAMICS-FRACTURE GRATING METHOD显示文摘The etching technique of the single-lined zero-thickness specimen grating is applied tothe surface of the SiC fiber toughening Si3N4 ceramic composite specimen.The position of the crackand the crack length during the process of crack extension when the load is applied and gradually in-creased can be determined by recording the output voltage value of the Wheatstone bridge in which theceramic specimen with the fracture grating on is located.The crack-growth-resistance(R-curve) of thismaterialis thus obtained. | Shi, L Dai, FL Jiang, XL | 1996 | Acta Mechanica Solida Sinica1996，9，1： | 0 |
