Finite Element Analysis of Discharge Antivibrational Pipe Stress State of the Piping System Flexible Joint

The paper studied the stress-strain state of the discharge antivibration pipe of the flexible joint of piping systems from the effects of overpressure. The estimation of the distribution of contact forces and stresses in the fastening elements of the pipe shell and contact areas with metal flanges has been carried out. Newmark method was used in solving problems with geometric nonlinearity.
