Abstract
The non-linear equilibrium conditions for irregular thin shells are formulated from the appropriate form of the principle of virtual displacements. 2D constitutive relations of elasto-plastic behaviour of thin shells are established by dividing the shell into n layers and then integrating the corresponding 3D constitutive relations throughout all layers at each step of non-linear incremental solution by FEM. As example, deformation and stress states in the casing of pressure measuring devise are calculated taking into account deformability of the junctions.
