Continuum elements
Elements tested
Continuum elements (excluding coupled temperature-displacement and pore pressure elements).
Problem description
The models consist of the same patches of elements used in the tests defined in Patch tests. The first step consists of an eigenvalue analysis of the model with no boundary conditions. The second step applies a uniform pressure load on all four edges and sets the NLGEOM parameter. The third step performs an eigenvalue analysis of the prestressed model with no boundary conditions. Results are printed only for the first and third steps.
Results and discussion
For all elements the number of zero-energy modes for Steps 1 and 3 is the same and matches the number of rigid-body modes given in Eigenvalue extraction for single unconstrained elements.
