Fatigue crack growth under mixed-mode I\u2009+\u2009II and I\u2009+\u2009III in heat treated 42CrMo4 steel
Abstract
The paper contains the results of an experimental investigation of fatigue crack development under mixed-mode I\u2009+\u2009II and I\u2009+\u2009III in heat-treated 42CrMo4 steel. Tests were performed on heat-treated compact tension shear specimens and rectangular cross-section specimens for mixed-mode I\u2009+\u2009III. Mixed-mode I\u2009+\u2009II tests were conducted for 30 and 60° loading angle, while the test for I\u2009+\u2009III mixed-mode was conducted for 30 and 45°. Additionally, the paper presents fracture analysis results of fatigue crack path development.
