… Bellows expansion joints are an integral part of many air or fluid supply systems in many
installations and vehicles. To solve the problem of determining the stress-strain state of the
bellows compensator in the air intake system of the aircraft, analytical methods are
ineffective due to the complex geometry, so it is advisable to use numerical methods of
calculation. To build a finite-dimensional model, three-dimensional finite elements in the
form of a tetrahedron were used. An analysis of the stress-strain … This work deals with the …
