Essay

On the base of three-dimensional theory of thermoelasticity and at the geometrically nonlinear statement the new finite element method for investigations of stress-strain states, stability and buckling behaviour of shells with geometric singularities by a thickness under thermoforce loads is developed. The new universal space finite element, which is eccentrically situated relatively the shell's middle, is developed. The reliability of obtained solutions is studied. It is investigated the influence of the parameters on the loss of a stability of the shells linear-variable thickness, with edges, channels, recesses, holes, breaks of middle surface at an operation of force and temperature loads.
