Results of numerical analyses of pipe section subjected to a three-point bending test enable numerical evaluation of deformation and analysis of the state of stress in both the contact area and that with imperfections. In the analysed instances plastic deformations of the object under examination is what we have to deal with. In the engineering practice such states could occur where the pipe contacts some other object(s) or when one pipe lies upon the other one. What happens is local loss of stability of the pipe’s cross-section. In consequence, effected are any kinds of folds or concavities.
