“…After nonlinearity correction, the fracture toughness increase along with the increase in specimen diameters (Figure 12B). This result is more reasonable according to the size effect of ligament areas of different CB specimens, which conforms to the general regularity by other researchers 2,20–22 . The ligament area increases with the increase of CB specimen diameters, leading to the increase of peak loads and then the mode‐I fracture toughness.…”

“…This result is more reasonable according to the size effect of ligament areas of different CB specimens, which conforms to the general regularity by other researchers. 2,[20][21][22] The ligament area increases with the increase of CB specimen diameters, leading to the increase of peak loads and then the mode-I fracture toughness. Therefore, the contrast in Figure 12 indicates that nonlinearity corrections are essential to improve the accuracy of test results and reduce data dispersion.…”

“…[14] Early corrosion at weak points may safeguard the remaining reinforcement [18]. Another study by [19][20][21] also examined the crack covering corrosion induced crack, fracture toughness and crack movement. A brief SEM identification on fracture parameters has been conducted by Akbari et al [22], Emadi and Modarres [23].…”

“…However, some parameters such as specimen size and crack angle also affect the fracture mechanics of the PC. 8 Although experimental evaluation of the fracture properties leads to very reliable results, it requires the process of fabrication and testing specimens, which are usually expensive methods. [9][10][11] The efficiency of neural networks (NN) in predicting the mechanical properties of some materials has been proven.…”

“…Materials type and weight content (wt%) are the crucial influencing parameters on the K Ic and CTOD. However, some parameters such as specimen size and crack angle also affect the fracture mechanics of the PC 8 . Although experimental evaluation of the fracture properties leads to very reliable results, it requires the process of fabrication and testing specimens, which are usually expensive methods 9–11 …”
