Plane bending fatigue tests were carried out on several kinds of hot-r
olled low-carbon steel sheets with texture to clarify the effects of t
exture on fatigue crack propagation. The crack growth rate of each mat
erial was determined uniquely by a term sigma(a)(n)l, where sigma(a) i
s nominal stress amplitude, l is the crack length, and n is a material
constant. The n exhibited different values according to the materials
, whereas there is not so much difference in the sigma(B) of each mate
rial. The different n in such materials may result from the difference
in texture. Moreover, the value of n tended to decrease with an incre
ase in r value, plastic anisotropy ratio. The analysis based on the sm
all-crack growth law, dl/dN = C-3(sigma(a)/sigma(B))(n)l, in which the
effect of a material property was considered, suggested that the effe
ct of texture on the value of C-3 is negligible. The reciprocal of C-3
represents the resistance to small crack propagation in each material
.
