Pressurized Orthotropic Container

Application ID: 12669

A thin-walled container made of rolled steel is subjected to an internal overpressure. As an effect of the manufacturing method, one of the three material principal directions—the out-of- plane direction— has a higher yield stress than the other two. Hill’s orthotropic plasticity is used to model the difference in yield strength. The example also shows how to define and use curvilinear coordinates aligned with the principal directions of the material, which in this case follow the contours of the container.

The container has the shape of a cylinder capped by two torispherical heads (also called Klöpper head).

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
