Publication: Journal of Engineering Mechanics
Volume 142, Issue 8
During composition, the exponential function in some equations was erroneously presented as the power function. The corrected equations are given as follows:
ε¯f=c1exp(c2η)
(14)
ε¯f=c3exp(c4η)[cos(π6θ¯)]c5[1+c6(χ0.5)]
(15)
dD=exp(c14κ)dε¯pcε¯f(η,θ¯)
(28)
dD=exp(c14κ)m(ε¯ptε¯f)m1dε¯pcε¯f(η,θ¯)
(29)
ASCE regrets the error.
The authors would like to correct two column headings in Table 2. The heading “Eq. (34)” should be “Eq. (24),” and the heading “Eq. (38)” should be “Eq. (28).” The correct table is as follows:

6(-0.130.25), [0.6]

Note: CTF = cyclic to failure; C-PTF = cyclic then pulled to failure. The specimens are cycled between displacement limits and subjected to tension load at the incipient stages. The displacements history is described with the following examples: for CTF, (0.130.26), [9,0.2] refers to specimen cycled between 0.13 and 0.26 mm until failure is observed on nine cycles at a 0.2-mm displacement; for C-PTF, 6(0.130.25), [0.6] refers to a specimen first subjected to six cycles with displacement limits of 0.13 and 0.25 mm and then pulled to failure at a 0.6-mm displacement.
