^aIt is normalized by the average compressive strength, f _c.
^bIt is normalized by the average strain at the peak stress, ε _o.
^cIt is normalized by the average elastic modulus, E _c.
^dIt is normalized by the average toughness index, I.
^eIt is normalized by the average ultimate strain, ε _ou.
^fNeglected data because the instability of descending branch after peak stress.
