Abstract
In this paper, three different directions of 0°, 45° and 90° were used to manufacture the Haynes 282 alloy bars by using the Direct Metal Laser Sintering (DMLS) method. The additively manufactured specimens as well as these of the wrought Haynes 282 were subsequently subjected to comparative fatigue tests in the range of stress amplitude from ±400 MPa to ±800 MPa. The AM process enhanced the fatigue response of the nickel-based alloy in question by 200 MPa. Furthermore, it was found, that the printing direction does not affect the fatigue response of additively manufactured specimens significantly as minor differences in service life were observed for the entire stress amplitude range adopted. Finally, fatigue damage measure φ and fatigue damage parameter D approaches were used to reveal the dynamics of damage development and to monitor damage development due to fatigue.
期刊介绍：
Featuring original, peer-reviewed papers by leading specialists from around the world, the International Journal of Damage Mechanics covers new developments in the science and engineering of fracture and damage mechanics.
Devoted to the prompt publication of original papers reporting the results of experimental or theoretical work on any aspect of research in the mechanics of fracture and damage assessment, the journal provides an effective mechanism to disseminate information not only within the research community but also between the reseach laboratory and industrial design department.
The journal also promotes and contributes to development of the concept of damage mechanics. This journal is a member of the Committee on Publication Ethics (COPE).
