Abstract

The mathematical models of damageability under static and cyclic loadings are investigated. The parameters of damageability and endurance are considered necessary for the calculation of long-term durability wear and low-cycle and high-cycle fatigue, thermo-cyclic endurance and deformation as well as general models, taking into account multi-axis and multicomponent loads. The models of damageability at loading range, the probabilistic models of endurance and accumulation of damage at random influence are given. Probabilistic criteria for service life estimation and their connection with accumulated damageability are researched.

A Holistic Approach to General Aviation Aircraft Structural Failure Prevention in Australia

“…These projects, some of them still in progress or under evolution, have led to the development of methods and equipment capable of acquiring, collecting and analysing flight load data (e.g. the Airframe Cumulative Fatigue Monitoring System -FAA 1994), as well as calculating the structural fatigue in GA aircraft structures (wing, fuselage, empennage, landing gear) through a probabilistic safe life approach (Ocampo, Millwater 2010;Ocampo et al 2011;Kulyk et al 2011). Also, some other low-cost technological devices (fatigue monitoring systems) have been developed in an effort to capture the GA aircraft market (e.g.…”
