There exist a number of classical analytical solutions for the calculation of the residual stresses produced by autofrettage. Historical solutions for thick‐walled tubes are based on assumptions, which are approximate in comparison with reality and limited in the range of applicability. New results for realistic boundary conditions reveal some unexpected phenomena.
