Эволюция напряжённого состояния и оценка работоспособности узла болтового соединения вязкоупругих композиционных пластин

Bolt joint of ortotropic viscoelastic plates, put with a gap, is investigated. The ends of plates are loaded with the constant evenly distributed stretching efforts. The task is solved in three-dimensional statement within the linear theory of viscoelasticity. The decision is made by a method of quasi-constant operators with final elements realization. The picture of evolution the tension joint even at constant external loading is received. The estimation of joint long-term durability within A. Ilyushin’s theory of long-term durability is made. Possibility of violation the immovability condition of a joint in a course of time is established. The dangerous tension, and also values of continuous external influence and characteristic times at which there is durability violation are determined.
