Damage Hazard Model for Chosen Element of the Aircraft Structure Taking Into Account Fatigue Crack Development Stages

Abstract: Abstract. The subject of the present paper is the modeling of aircraft structure fatigue processes which endanger flight safety. It is assumed that the simple course of the process of aircraft structure elements fatigue encompasses the following stages: initiation of cracks, crack development to the limit value, destruction of the element of structure . These stages can be taken as random incidents or random processes. The paper provides a description of the two initial stages as random processes. The relation… Show more
