A response surface maximum point was obtained, and the critical values were a concentration of 0.13 mmol L− 1 PAN, 0.03% m/v Triton X-114 and 2.3% m/v NaCl.
Also, because of brittle fracture behavior of adhesive joint in this study, the maximum point was proposed as critical load at failure (initial crack propagation) [33].
Comparing the amplitudes of these two maximum points, and the bigger one was chosen as the final maximum point, under the premise that dP was within the normal range; (b) When dW 1 was within the normal range, if no maximum point was identified between two minimum points and dW 2 was beyond the normal range, then a maximum point was missing.
Comparing the amplitudes of these two maximum points, and the bigger one was chosen as the final maximum point, under the premise that dP was within the normal range; When dW 1 was within the normal range, if no maximum point was identified between two minimum points and dW 2 was beyond the normal range, then a maximum point was missing.
After further analysis of the data between the two minimum points and estimation of the value of dP, the missing maximum point was found out; (c) When dW 2 was within the normal range, if two minimum points were identified between two maximum points and this dW 1 was below the lower limit, then a minimum point was detected false.
Comparing the amplitudes of these two minimum points, and the smaller one was chosen as the final minimum point, under the premise that dT was within the normal range; (d) When dW 2 was within the normal range, if no maximum point was identified between two minimum points and dW 1 was out of the normal range, then a minimum point was missing.
