fis-1791	Berto, Filippo; Campagnolo, Alberto; Meneghetti, Giovanni; Tanaka, Keisuke	Averaged strain energy density-based synthesis of crack initiation life in notched steel bars under torsional fatigue	2016	9	.pdf	application/pdf	4462	277	56	In circumferentially notched bars subjected to torsion fatigue loadings, factory-roof type fracture surfaces are obtained under low stress amplitudes and the sliding contact of the fracture surfaces causes the retardation of crack propagation [8–12]. However, the effects of sliding contact and/or friction between fracture surfaces during the propagation phase are evident, because the experimental results in terms of total fatigue life (see the smaller symbols: the black ones are related to pure torsion fatigue loading, while the gray ones are for torsion fatigue loading with superimposed static tension) are characterized by a high scatter, due to the difference between the fatigue lives of specimens tested with and without static tensile stress.	cache/fis-1791.pdf	txt/fis-1791.txt
