Pinched Hemispherical Shell

Application ID: 8532

This example studies the deformation of a hemispherical shell, where the loads cause significant geometric nonlinearity. The maximum deflections are more than two magnitudes larger than the thickness of the shell. The problem is a standard benchmark, used for testing shell formulations in a case which contains membrane and bending action, as well as large rigid body rotation.

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