Shell's structural members. Development of the method for thermal and irrationed creep and durable strength calculations for structural shell's elements. The methods are: computer numerical simulation using FEM, method predictor-corrector. Model of nonlinear deformation and the method of numerical analysis of stress-strain state of non-axisymmetrical shells of revolution for creep-damage are developed, the new laws of creep and damage of structural shell's elements are established. The new method of calculations for the first time allows to perform the scientifically based estimations of durable strength shells loaded by static, dynamic and radiation actions. The results of calculations and conclusions has been used in NSC KhFTI. The sphere of use is machine building.
