Negative side effects of corrosion preventive compounds on aircraft fatigue and criteria for their selection https://doi.org/10.33108/visnyk_tntu2019.04.051
Main Article Content
Abstract
The necessity and possibility to reveal probable negative side effects of Corrosion Preventive Compounds on fatigue of aircraft structural members is shown. Three mechanisms of the side effects are considered: a) redistribution of loads on the riveted components due to the reduction of friction; b) influence on fatigue crack propagation; c) influence on fatigue crack nucleation. Experimental methods to reveal negative side effects are proposed.
