Flambage plastique des coques de révolution sous pression interne

Abstract : Shells of revolution and in particular, torispherical or elliptical shells present a local buckling under internal pressure. To predict correclty the critical loads, the plastic buckling has been considered. Thus, the critical pressure has been determined numerically, using classical models of plasticity and numerical code. Often this computation (torispherical or elliptical shells), takes a long numerical time. That is why it is better to have accurate analytical estimations of the buckling load. In this respect a new simplified buckling analysis has been introduced and worked out
