It is defined by eight nodes having three degrees of freedom at each node: translations in the nodal x, y, and z directions. The element has plasticity, hyperelasticity, stress stiffening, creep, large deflection, and large strain capabilities. It also has mixed formulation capability for simulating deformations of nearly incompressible elastoplastic materials, and fully incompressible hyperelastic materials. See SOLID185 in the ANSYS, Inc. Theory Reference for more details about this element. A higher-order version of the SOLID185 element is SOLID186. Figure 185.1  SOLID185 Geometry SOLID185 Input Data The geometry and node locations for this element are shown in Figure 185.1: "SOLID185 Geometry". The element is defined by eight nodes and the orthotropic material properties. The default element coordinate system is along global directions. You may define an element coordinate system using ESYS, which forms the basis for orthotropic material directions. Element loads are described in Node and Element Loads. Pressures may be input as surface loads on the element faces as shown by the circled numbers on Figure 185.1: "SOLID185 Geometry". Positive pressures act into the element. Temperatures may be input as element body loads at the nodes. The node I temperature T(I) defaults to TUNIF. If all other temperatures are unspecified, they default to T(I). For any other input temperature pattern, unspecified temperatures default to TUNIF. Similar defaults occurs for fluence except that zero is used instead of TUNIF. KEYOPT(6) = 1 sets the element for using mixed formulation. For details on the use of mixed formulation, see Applications of Mixed u-P Formulations in the ANSYS Elements Reference. You can apply an initial stress state to this element through the ISTRESS or ISFILE command. For more information, see Initial Stress Loading in the ANSYS Basic Analysis Guide. Alternately, you can set KEYOPT(10) = 1 to read initial stresses from the user subroutine USTRESS. For details on user subroutines, see the Guide to ANSYS User Programmable Features. As described in Coordinate Systems, you can use ESYS to orient the material properties and strain/stress output. Use RSYS to choose output that follows the material coordinate system or the global coordinate system. For the case of hyperelastic materials, the output of stress and strain is always with respect to the global Cartesian coordinate system rather than following the material/element coordinate system. The effects of pressure load stiffness are automatically included for this element. If an unsymmetric matrix is needed for pressure load stiffness effects, use NROPT,UNSYM. "SOLID185 Input Summary" contains a summary of element input. For a general description of element input, see Element Input.

KEYOPT(2) Element technology: 0 --  Full integration with method 1 --  Uniform reduced integration with hourglass control 2 --  Enhanced strain formulation 3 --  Simplified enhanced strain formulation KEYOPT(6) Element formulation: 0 --  Use pure displacement formulation (default) 1 --  Use mixed formulation KEYOPT(10) User-defined initial stress: 0 --  No user subroutine to provide initial stresses (default). 1 --  Read initial stress data from user subroutine USTRESS Note See the Guide to ANSYS User Programmable Features for user written subroutines. SOLID185 Element Technology SOLID185 uses the method (also known as the selective reduced integration method), the uniform reduced integration method, or the enhanced strain formulation method, as follows: · method (selective reduced integration) Helps to prevent volumetric mesh locking in nearly incompressible cases. This option replaces volumetric strain at the Gauss integration point with the average volumetric strain of the elements. This method cannot, however, prevent any shear locking in bending dominated problems. In such situations, use the enhanced strain formulation of this element. If it is not clear if the deformation is bending dominated, enhanced strain formulation is recommended. For more information, see the ANSYS, Inc. Theory Reference. · Uniform reduced integration Also helps to prevent volumetric mesh locking in nearly incompressible cases. Because it has only one integration point, this option is more efficient than the method (selective reduced integration) option. However, the artificial energy introduced to control the hourglass effect may affect solution accuracy adversely. When using this option, check the solution accuracy by comparing the total energy (SENE label in ETABLE) and the artificial energy (AENE label in ETABLE) introduced by hourglass control. If the ratio of artificial energy to total energy is less than 5%, the solution is generally acceptable. If the ratio exceeds five percent, refine the mesh. You can also monitor the total energy and artificial energy by issuing the OUTPR,VENG command in the solution phase. For more information about uniform reduced integration, see the ANSYS, Inc. Theory Reference. · Enhanced strain formulation Prevents shear locking in bending-dominated problems and volumetric locking in nearly incompressible cases. The formulation introduces 13 internal DOFs (inaccessible to ANSYS users). If mixed u-P formulation is employed with enhanced strain formulation, only 9 DOFs for overcoming shear-locking are used. All internal DOFs are introduced automatically at the element level and condensed out. Because of the extra internal DOFs and static condensation, this option is less efficient than either the method (selective reduced integration) option or the uniform reduced integration option. For more information about enhanced strain formulation, see the ANSYS, Inc. Theory Reference. · Simplified enhanced strain formulation Prevents shear locking in bending-dominated problems. This is a special case of the enhanced strain formulation and always introduces 9 internal DOFs (inaccessible to ANSYS users). Because there are no internal DOFs to handle volumetric locking, this formulation should not be used when the material is nearly incompressible, except when the Mixed u-P formulation is also used. When used with the Mixed u-P formulation, the simplified enhanced strain formulation gives the same results as the enhanced strain formulation. All internal DOFs are introduced automatically at the element level and condensed out. Because of the extra internal DOFs and static condensation, this option is less efficient than either the method (selective reduced integration) option or the uniform reduced integration option, but is more efficient than the enhanced strain formulation due to using fewer internal DOFs. For more information about the simplified enhanced strain formulation, see the ANSYS, Inc. Theory Reference.

The element may not be twisted such that the element has two separate volumes (which occurs most frequently when the elements are not numbered properly). · All elements must have eight nodes. You can form a prism-shaped element by defining duplicate K and L and duplicate O and P node numbers (see Triangle, Prism and Tetrahedral Elements). A tetrahedron shape is also available. · For the degenerated shape elements where the or enhanced strain formulations are specified, degenerated shape functions and a conventional integration scheme are used. · If you use the mixed formulation (KEYOPT(6) = 1), you must use either the sparse solver (default) or the frontal solver. · For modal cyclic symmetry analyses, ANSYS recommends using enhanced strain formulation. · Stress stiffening is always included in geometrically nonlinear analyses (NLGEOM,ON). It is ignored in geometrically linear analyses (NLGEOM,OFF) when specified by SSTIF,ON. Prestress effects can be activated by the PSTRES command.
