Effect of shot peening intensity on surface integrity of 18CrNiMo7-6 steel
TL;DR: In this paper, the effect of different shot peening parameters on the peening intensity and the influence of which on surface integrity parameters of carburized steel rollers was explored. And the intensity was mainly affected by the shot diameter (36.73%), air pressure (32.07%), and shot flow rate (23.11%).

A new multiaxial fatigue life prediction model for aircraft aluminum alloy
TL;DR: In this paper, a new multiaxial fatigue life prediction model was proposed for both thin-walled tubular and notched specimens, and a new characteristic plane (subcritical plane) was defined to describe the particularity of additional cyclic hardening under non-proportional loading condition.

Micromechanical analysis of gear fatigue-ratcheting damage considering the phase state and inclusion
TL;DR: In this paper, the impact of subsurface inclusions and grain boundaries on the ratcheting damage was investigated, where the crystal plasticity framework was implemented to model different phase states, describing the stress-strain response on slip systems, and the influence of different phases including martensite and austenite around the inclusion on the damage accumulation was also investigated.

A Theory for Fatigue Failure under Multiaxial Stress-Strain Conditions
M. W. Brown,K. J. Miller +1 more
TL;DR: In this article, a new theory for multiaxial fatigue is presented that is based on a physical interpretation of the mechanisms of fatigue crack growth, represented graphically by contours of constant life, which are expressed mathematically bywhere e1, e2 and e3 are the principal strains, •e1 ≥ e2 ≥ e3.

The effect on fatigue life of residual stress and surface hardness resulting from different cutting conditions of 0.45%C steel
TL;DR: In this paper, the effect of the machining conditions on the fatigue life was investigated through a fatigue test using the specimen finished under various cutting conditions, and it was shown that it is possible to get longer fatigue life for machined parts than the virgin material or the carefully finished material without affected layer.
