... that the injection rate or loading rate has little effect on FIP. (3) With the increase of injection rate and loading rate, the tensile strength and FBP first decrease and then increase, and the critical loading rate is 0.09 MPa/s. In order to obtain a wider injection pressure range, the injection rate should be far...
