- Average of 7 tests; fcr—axial fiber stress at the first cracking; εcr—axial strain at the first cracking; E*—slope of the line of the stress–strain plot connecting the origin and the cracking point; ffu – axial fiber stress at ultimate; εfu—axial strain at ultimate; Ef – stiffness of C-FRCM determined using Eq. (1).
