In modelling the behavior of thick-walled metal shells under compressive loads, the use of J2 flow theory can lead to unrealistic buckling estimates, while alternative ‘corner’ models, despite offering good predictions, have not been widely adopt

Non-associative plasticity for structural instability of cylindrical shells in the inelastic range

Autor: Nasikas, Apostolos

Thick-walled cylindrical metal shells, commonly used in tubular structures and pipelines, during their lifetime may be subjected to considerable compressive loads, which can lead to local buckling. In modelling their structural behaviour, the use of
