Modeling of the boundary conditions when calculating the stress-strain state of a cone-shaped aircraft nose fairing

The stress-strain state of a cone-shaped aircraft nose fairing is studied. The structure is loaded with external pressure at high temperatures. The cone-shaped fairing has a weakened section with a modified value of the elastic modulus. The boundary value problems are solved with a controlled error. Based on the calculation results, it is concluded to simulate the boundary conditions in the form of a conjugation of a cone-shaped fairing with a cylindrical body.
