Over the years, the flight safety has become a matter of prime concern due to several fatigue failures of structural components and the need to prevent them. Among these, large number of fatigue failures was initiated at major discontinuities such as the inevitable structural joints. Due to this, structural health monitoring (SHM) at these critical locations has become a crucial aspect in the modern damage tolerance-based design concept. Lug joints are often preferred in large-scale structural components which act as primary load-carrying members and are more susceptible to failure due to high stress concentration and geometric irregularities. The primary issue in the analysis of these joints is the loss of contact between the pin–hole boundary during loading and possible change in contact conditions during fatigue loading. This paper deals with the behaviour of tapered attachment lug joints under fatigue loading and finally presents prognostic analysis to estimate remaining life of the joints at any instant of fatigue cycles. |
