Such a definition can give rise to a seam, or crack, in the surface as shown in Figure Similar problems can occur for finite-sliding, surface-to-surface contact.

The cracks will appear as extra perimeter lines in the interior of the surface. Duplicate nodes can be abaqus documentation 6 11 easily by equivalencing nodes when creating the model in a preprocessor.

Avoiding problems with contact along the perimeters of surfaces When modeling finite-sliding contact, ensure that the master surface definition extends far enough to account for all expected motions of the contacting parts.


Contact along the perimeter of master surfaces should be avoided. A slave node that falls off a master surface in one iteration may find itself contacting the surface in the very next iteration; this phenomenon is known as chattering. This problem is less likely abaqus documentation 6 11 the surface-to-surface formulation approach, because each contact constraint is based on a region of the slave surface rather than individual slave nodes.

The small-strain shells and beams should not be used in finite-strain analysis with either elastic-plastic or hyperelastic material behavior, since incorrect analysis abaqus documentation 6 11 may be obtained or program failure may occur.

Nominal strain The nominal strain, NE, is where is the left stretch tensor, are the principal stretches, and are the principal stretch directions in the current configuration.

The principal values of nominal strain are, therefore, the ratios of change in length to length in the reference configuration in the principal directions, thus giving a direct abaqus documentation 6 11 of deformation.

Logarithmic strain The logarithmic strain, LE, is where abaqus documentation 6 11 variables are as defined earlier for nominal strain.

Abaqus Release Notes This manual contains brief descriptions of the new features available in the latest release of the Abaqus product line. In the HTML documentation, use any of the following methods: Use the back and forward arrows in the text frame abaqus documentation 6 11 navigate sequentially through the text.

For elements that use a corotational coordinate system finite-strain shells, membranes, and solid elements with user-defined orientationsthe above equation simplifies to The strain increment is obtained by integration of the rate of deformation over the time increment: This strain measure is appropriate for elastic- visco plastic or elastic-creeping materials, because the plastic strains and creep strains are obtained by the same integration procedure.

In such materials the elastic strains are small because the yield stress is small compared abaqus documentation 6 11 the elastic modulusand the total strains can be compared directly with the plastic strains and creep strains.

If the principal directions of straining rotate with respect to the material axes, the abaqus documentation 6 11 strain measure cannot be related to the total deformation, regardless whether a spatial or corotational coordinate system is abaqus documentation 6 11.

Abaqus Example Problems Manual This manual contains detailed examples designed to illustrate the approaches and decisions needed to perform challenging, real-world linear and nonlinear analysis.

Many of the examples are worked with several different element types, mesh densities, and other variations.
