Load sequence effects on the fatigue crack growth in a cylinder subjected to combined rotary bending moment and axial force loads

Weight function for an external circumferential semielliptical crack in a cylinder

“…Dao and Vu 14 used the FEM to model the fatigue growth of a semielliptical external crack in a cylinder subjected to rotary bending and axial load. Okada et al 15 developed a procedure on the basis of the FEM to solve internal semielliptical cracks with high aspect ratios in plate and cylinder.…”

Characteristics and damage mechanisms of bending fretting fatigue of materials

“…Rotating bending was studied for crack growth in a press-fitted test rig (Savaria et al., 2016; Yang et al., 2014; Yuan et al., 2014). In recent years, a number of studies on bending fatigue (Dao and Vu, 2016; Goidescu et al., 2015; Haidyrah et al., 2016; Hwang et al., 2016; Kamaya, 2016; Li et al., 2016; Ma et al., 2015) and fretting fatigue have been reported (Foletti et al., 2016; Huang et al., 2016a, 2016b; Shi et al., 2016; Winkler et al., 2015), whereas comparatively less studies were performed on bending fretting fatigue (Ding et al., 2014; Johnson, 1995; Liu et al., 2013). In the present study paper, test rigs for bending fretting fatigue are classified into reciprocating and rotary types, which are subdivided into branches.…”
