Pressurized Orthotropic Container — Shell Version

Application ID: 78091

A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, the out-of- plane direction has a higher yield stress than the other two directions. Hill’s orthotropic plasticity is used to model the difference in yield strength. The container is made by a cylinder capped by two torispherical heads (also called Klöpper head).

In this example, plasticity is modeled in the Shell interface. Axial symmetry is used.

This model example illustrates applications of this type that would nominally be built using the following products:
