Product: ABAQUS/Standard
Acoustic elements, beams, cohesive elements, elbows, membranes, pipes, shells, trusses, continuum elements (except coupled pore pressure-displacement and coupled temperature-displacement elements), piezoelectric elements, springs, and masses.
The models consist of a single element. There are no boundary conditions, except as required in spring-mass (see “SPRING, MASS, and JOINT2D elements”) and piezoelectric tests. For the piezoelectric element tests one electric potential degree of freedom is constrained to remove singularities from the dielectric portion of the structural stiffness.
Note: There are no mass terms associated with potential degrees of freedom.
The results presented in Table 1.2.1–1 through Table 1.2.1–7 show the number of zero-energy modes and the first nonzero eigenvalue. Some elements have nonrigid-body zero-energy modes. Where two values are given in the zero-energy modes column, the first is the number of zero-energy modes and the second is the number of rigid-body zero-energy modes. When an assembly of elements is tested, as in “Eigenvalue extraction for unconstrained patches of elements,” Section 1.2.2, the nonrigid-body zero-energy modes disappear. The eigenvalue is shown only for purposes of comparison. Elements with quadrilateral geometry can be degenerated to triangular shape; these results are denoted by “(triangle)” in the tables. Results for the piezoelectric elements are reported for Step 2.

The models for the eigenvalue extraction tests for SPRING and MASS element types are slightly more complex than the tests for the other elements.
Elements of type SPRINGA and MASS are tested together in file exspame1.inp. Three nodes lie along a straight line. One of the nodes is constrained, and each of the other two nodes defines a point mass. SPRINGA elements are defined between each of the three possible pairs of nodes. The spring-mass system acts in degree of freedom 1.
File exspbue1.inp tests element types SPRING1 and SPRING2 with a mass matrix defined by a user element. Two coincident nodes are defined. These two nodes are used in the definition of the user element. A SPRING2 element connects the nodes, and each node is also connected to a SPRING1 element. No boundary conditions are required since, by definition, the other ends of the SPRING1 elements are connected to ground. The spring-mass system acts in degree of freedom 1.
Results for both tests: 
=0.6340, 
=2.3660.
File exepxme1.inp tests element type JOINT2D. One node of the JOINT2D element is fully constrained, and the other has MASS and ROTARYI elements applied to create a spring-mass system. The natural frequencies and modes correspond to analytically calculated values.
